For many years I drove a car with the later generation Poly engine, a 63 with a 318 V-8. It was very smooth and rock sold reliable, but no hot-rod. I look forward to the future episode on that variant of the Poly engine.
That’s awesome is the 318 poly the same engine that they used in the 70s with the lean burn technology if that’s the case I drove one I thought that was pretty cool I almost bought a Chrysler Córdoba 1976 I had a thing for those but I didn’t like the Excelerator pedal it was super heavy it almost seems like the return spring was too stiff.. Definitely going to cover Chrysler A engine family in another episode this one was just to explain the poly head version of the hemi V8
@@What.its.like. The 318 Poly was the "A" Engine. Was replaced by the "LA" in the mid 60's, which I believe was the basis for the 273 - 360 engines that were used until the 80's. There were some similarities and interchangabilities, but overall they were different engines. The Poly was very cool, but it was heavy and did not produce good fuel economy. ("LA" stood for "Light A", I believe.) That's my understanding, anyway!
Chrysler’s engines are confusing I thought Ford was confusing with overlapping engine families definitely going to cover both eventually It seems like Chevy with their small block design got a lot right and they don’t have a whole bunch of engine Families that overlap one another not saying it’s perfect because the very first year of the 265 they had oiling issues just like the Y block had oiling issues but when they got the kinks worked out it just worked Thank you so much for sharing all that insight and information I greatly appreciate it =)
As I remember the early 318 was a stouter and heavier duty engine than the 318 of the 1970s,the earlier 318 was mostly found in Dodge Trucks but I think a version was in the earliest Barracudas. The later light 318 and especially the "Lean Burn" version I thought used more rather than less gasoline and the "Lean Burn" was not as powerful.
Between 1955 and 1958, Chrysler made a bewildering array of V-8 engines that are difficult to keep straight. It is a wonder that Chrysler didn't go broke trying to make parts for all of these engines. Thank you for a good introduction to this engine family.
Yeah it’s super confusing all of the different array of engines as you mentioned they also introduced other engines midyear that’s why a lot of people get really confused with the 318 engine in the 350 engine because they were introduced during this engines life even though they’re nothing like this engine this engine only correlates with the hemi blocks.. glad you dig this episode =)
@@What.its.like. The 350 engine was the first of the B-Block engines that led to the 361, 383, and 400 engines. (The 413, 426 and 440 engines were RB engines.)
Good explanation of the Polysphere engine design. To elaborate a little, they started with the Hemi but wished to make a cheaper, simpler, lighter engine. So they kept the hemi design including the block, intake manifold etc and just changed the heads, mainly on the exhaust side. Left the intake side alone but moved the exhaust valves up and closer to the intakes, putting both exhaust and intake rockers on the same shaft and making the head narrower and lighter. This required a different combustion chamber shape, slightly smaller valves, pistons with different shaped crown and of course, different head casting. Other than the heads pistons and exhaust other parts were alike and interchangeable. The result was very close to the hemi in performance. A 1956 Windsor would run with the hemi New Yorker or Imperial right up to 80 MPH. After that the big blockbuster pulled ahead.
First choice 1955 Dodge,(the rare Texan edition only saw 1 at a car show), the 1956 Windsor ht. Another great engine episode. Watched the Hagerty video on the Turbine cars, and the engineers left interviewed, an hour long but packed with a lot of history.. Don't forget the GMC V6 truck engines
1966 dodge charger you could get a poly 318. 1967 charger you could get a LA 318. Even though some claim Mopar didn't release the LA 318 until 1968. We found a 1958 Plymouth wagon, and it had a 4 V carb option, for the 318 poly we had. The poly 318 ran pretty well with either carb, but the 4V carb was pretty spicy!
great episode that explains in detail the difference between the early 50's Chrysler Hemi-head engines and the mid 50's Chrysler Polyhead engines. Anyway you put it Chrysler made good engines back then with lots of power. Looking forward to your episode on the revolutionary 1955 Chevrolet small block engine. I know its coming soon!
Definitely going to cover the small block Chevy episode I’m not entirely sure when it’s going to take a long time to put that one together there’s tons of information to go over and tons of different engine configurations because Chevy didn’t have to re-engineer their block like all the other companies did like Ford and Chrysler ford had the y block, FE, Windsor small block (I might be missing one ) Chevy did not have all those engine families they just had a small block Chevy engine family which ran from 1955 all the way up until 2003
Definitely going to cover that engine family eventually there was just so many different engine displacement and this one to make it into one huge episode there’s a lot of displacements in that family as well.
The 1955 Chrysler Windsor, in both scenarios. It was much better built than its corporate companion makes, and lacked the pushbutton transmission selectors introduced in 1956. Anyone who had a '55 Chrysler will tell you that it was a superbly-built car that gave excellent service. The '57 Chrysler corporation cars tended to rust out. The '55 Chryslers did look gimmicky, like the last iteration of a body style rather than the first, but their solidity garnered affection.
Yeah I guess Chrysler products have sort of a gimmicky Ness about them but I honestly think when I see one at a car show especially one from the mid50s they look incredible now I wasn’t around when the cars first came out I wish I was I was born too late.
Chrysler bought the Briggs body works in 1953 when Walter Briggs died. They began to produce bodies in house. Briggs built bodies for other makes, but with Chrysler as the new owner those orders ceased. They hastily began cost cutting that produced a reputation for rust. Eventually they decided upon assembling the bodies at the assembly plant - the unitized body, which produced better results. The older Briggs body Mopars were well built.
I totally agree this is my favorite era of Mopar don’t get me wrong I like the big fans as well but the cars weren’t huge and 55 or 56 but still had tons of cabin space the other two Ford and Chevy have nowhere near rear leg room space as a Chrysler product one day I’m going to get in there with a tape measure and show how much more space is in a mid 50s Chevy ford and dodge product
I drive an all original turquoise and sand color 1955 Plymouth Belvedere with 24000 miles and enjoy my powerful 260 Polysphere V8. She is fast when needed. When I lift hood at car shows there are endless conversations and questions. :)
That’s awesome what do you like the most about your 55 what do you like the least I love Plymouth from that era they have so much space inside them even the two-door version I would take a 56 Plymouth anything over 57 Chevy anything I just love the styling of a 56 Plymouth also thinks Chevy ripped off the rear end design
For WYR, I'd pick the Plymouth Belvedere and the '57 Chrysler Windsor. Although the '56 looks pretty good to me, too. Thank you for giving the background to this engine.
Great choices this age and Family or version is a weird and obscure one and I had to cover it before I cover the next poly engine family Chrysler had a Lot of engines they had more engines and Ford and I thought Ford had a lot of different engine families I’m not sure what the next engine episode is going to be I really want to do one on the Hudson twin h I like to cover some obscure ones before I get into some main stream ones but it might be the small block Chevy who knows it depends on how much time I have I’m gonna need a lot of time to put that one together
56 Plymouth Belvedere 57 Windsor I owned a 64 Dodge Coronet four-door sedan and it had the 318 A series engine. Or what many called the wide block engine in it. It also had the polyspherical heads just like these early polyhead engines did. However the black was different and IIRC not the hemi-style block. The 318 and was bone stock when I bought the car used. Had a push button torque flight tranny. Being a junior in high school, I wanted to beef it up to get more horsepower out of it. I ended up being able to source a four-barrel manifold for it and I remember it was a for a Carter carb. I can't remember exactly which carb I ended up putting on there. It would have either been a WCFB or an AFB. I wanted to get a set of headers as well but I could just never find a set. It was a really solid well running engine with lots of power and torque. More than enough to move that Dodge sedan down the road. The A series wide block engines never attained the Hot rod mystique of the small block Mopar series engines that followed it. Pretty hard nowadays to find any kind of replacement performance parts for the A series wide block engines. I do remember though that those were big wide engines when you open the hood of that Dodge the engine literally took up the whole engine compartment.
It's kinda funny that everyone refers to the Poly 318 as a wide block, because it's the same width block as the 318 LA. The heads are what made the Poly 318 so wide, not the block.
@@johneckert1365 as someone who's owned a 64 Dodge with the A series engine. There is a difference in the blocks of the A series engines which were made from the mid 50's through 1966. And the later LA small block engines. 273,318,340,360. Very few parts interchange between the A and LA engines. Another reason I know this is because I blew the A series wide block engine in my 64. It threw a rod, cracked a piston, and pretty much tore up the short block badly. I found out real quick while searching for a replacement that the later series LA engines commonly referred to as the Mopar small blocks were entirely different. Now the early poly head engines did use the same block as the hemis of that era. But the heads were different being a poly design rather than the true hemi design.
@carlmontney7916 My bad, I meant to state that Poly 318 vs LA 318 blocks were the same width. They did share quite a few parts in common. The crankshaft and camshafts were the same/interchangeable. The timing gears, timing cover, fuel pump, water pump, etc were the same. You're definitely correct though, the blocks are not the sane and don't interchange. Many people wonder why LA engines have that weird lifter angle (rather than 90 degrees like most V8 engines. It because it uses the 318 Poly engineering. The Poly had to have that weird angle for the wonky valve train to work correctly. It was "good enough" for the LA engines, so no need to re-engineer them.
@@johneckert1365 and any mass produced item regardless of what it is if you have something that has worked you will continue to use it since you already set up to produce it.
1956 Belvedere 1956 Windsor The Dodge Le Femme is an expensive car 😱 pretty rare .. I always liked DeSoto The 55 DeSoto Hemi had some torque and ran strong 1 year only 😢 Fire Dome was a decent motor but pretty heavy 700 pounds ... We put them in model A fords 😂 hit the brakes on disck brakes and lift the rear of the car and Drift around backwards 😧😂 .. Never played with poly's to much sm block Chevy is King !!!!!!!! 🤔 Great episode and Happy Motoring ✌️🤠
Great choices =) 1955 desoto is a great looking car might be my favorite desoto 56 Belvedere is a great car as well I remember I reviewed one last year and I was really impressed with the space inside
Different engine family It’s confusing Plymouth got that engine in 1955 midyear but it’s a different engine family that is part of the Plymouth a series
Canadian 303 was a unique version of the Plymouth poly, meant for Canadian made Dodge and Chrysler Windsor models. Because this was the only V8 the Canadian engine foundry was equipped to make. It was borrowed for the US made 1956 Plymouth Fury because it was a direct bolt in replacement for the 270. It made the Fury quite the hot performer for the time, faster than an 283 Chev or 272 Ford.
I prefer the look of the ‘55 Windsor, but ‘56 would bring 12 volt electrics and push button powerflite transmission. In the end though, I’d still take the ‘55, I’m partial to it as I owned a ‘55 4 door, two tone light green and white. How about the 413? I have a 300F with all original drive train. I believe that the letter car blocks were specially selected, maybe your research my turn up some interesting factoids. Great research!
Definitely want to do the wedge family on here eventually Chrysler did a lot of different engine concepts just like Ford I was amazed at how many different engine families Ford had I had no idea Chrysler had more.. Not only that every year they change their engine displacement no wonder Chrysler ran out of money.. Thank you so much for adding that information what was your favorite thing that you liked about your 55 and what did you dislike the most Glad you dig this episode =)
I remember one in a yale forklift where I worked almost 50 years ago, when I was 18 yrs old. I abused that forklift badly, like very badly… I remember the exhaust manifolds glowing orange after holding it to the pin, for a long time, and I did that many many times, it never suffered any ill effects the three years I worked there, and still ran as good as ever when I quit.
WYR 1: Plymouth Belvedere (Dodge La Femme only if it actually came with all the cheesy accessaories!). WYR 2: 1957. Can't beat that peak Forward Look styling.
Ha ha ha ha yes the Dodge life femme would definitely have to have all the quirky cheesy accessories I want to cover one I have not seen one in the wild I can’t wait to go back to Classic auto Mall and get back to the glove box test and get back to the way that we used to do things don’t get me wrong I love doing cars a car shows it’s just different.. i’m not gonna be able to go back to Classic Automall until sometime next month I’m gonna try to go early November either late this month or early November I got so much stuff in the pipeline I don’t really have to go I got stuff left over for months..
Good Video. The Poly engines are often overlooked but were a very good engine in their own right. Often overlooked is there performance potential. An interesting tidbit is that while the 1956 Chrysler 300 (354 cubic inch)354 HEMI made more HP than the top of the line 1957 354 Poly, the 354 Poly actually made more torque than the HEMI (per the factory shop manual). It was also said the the reason for the the introduction of the Poly was that it was lighter and cheaper to produce than the HEMI. I'm sure it was cheaper, however the weight difference was pretty negligible. Both engines used the same block, intake manifolds and accessories (the exhaust manifolds don't interchange). I personally weighed a 1955 Chrysler 331 HEMI head and a 1955 301 Poly head (on the same scale). The Poly head was lighter.......by a whole 1 pound.
Awesome information thank you so much for sharing all that information and insight glad you did this video I love an engine episode Wednesdays this Wednesday push it back a little bit I’ve had a lot going on in the background which I will make my random moment tomorrow a lot of cool stuff built =)
In the early 6❤0’s I think we had a ‘55 Windsor. Occasionally on highway trips, it would die at a stop sign. I remember Dad talking about aluminum heads and vapor lock. After 5 minutes or so it would restart and we went merrily on our way. I wish I had been a camera nut when I was a kid so that I would have pictures of all the cars Dad and Grandpa and others had.
Chrysler Corporation, if you think about it did the outside box approach they first started with hemi head engines and then went poly head and then introduced the wedge
Glad you dig this episode It took me all day to put this one together, To the point my wife commented and said you’ve been working on that since 630 this morning it would’ve been done sooner but I had to take my daughter to gymnastics lol
55 Le femme and a 55 Windsor . I completely agree with you over the wasted time,effort and money spent on all the variations of the same engine and lack of co operation between the divisions.
That always amazed me that they were able to spend that kind of money and not have any repercussions for decades later the whole turbine engine project was really cool and why they got rid of that they had some thing that would runoff of anything that was combustible, I’m not a conspiracy theorist but I honestly believe that that’s why the government has bailed out Chrysler as many times as they did because they killed that program.. if you look back at the timing of when that program met its demise just a few years later gasoline shortages started happening.. Awesome choices =)
The poly is a neat engine. It would been nice to see a revised light casting as its heavy and wide. I think only the Chrysler 331-354-392 should have had the hemi heads. Dodge, DeSoto and Plymouth should have used a common simpler engine. The Chevy small block wedge was the best because of low costs and most weaknesses couid be overcome with aftermarket parts. The complex Mopar valve trains didn't shine as much in family cars as engineers hoped - they loved the race track. A big block version of the Poly might have been cool.
Gmc made a v12 it was two v6 put together that shred a common crank i didn't see it unless i looked over it but i all ways throught they where neat ... Great video 👍👍👍👍
That's not accurate. Yes mathematically the 702 V-12 was two 351 V-6 engines put together, but that's not what it was. The V-12 did have 1 crankshaft like you mentioned, but it was also 1 block, not two V-6 blocks put together like many assume. It was a 1 piece block for V-12 only. The heads are what give people that impression, because the do use V-6 heads. So there's 4 cylinder heads and 4 valve covers. Just 1 block, 1 crankshaft, 1 camshaft, 1 oil pan, etc......
Those cars are really sweet that’s one of my biggest regrets not doing at Hershey there was a couple 300s there I wish I would’ve done one there was some big fin Plymouth there as well but they will all be on the channel eventually =)
I have a 66 Dodge Travco Motorhome with 318-3 Heavy Duty “A” Engine this one is obscure but I really like it. Hydraulic lifters and rotating exhaust valves. Used on S-500 school bus chassis.
Outstanding presentation on this family of engines! The organization following the family line really made something complex flow more smoothly. WYR: 1955 Windsor, and 1957 Windsor. Thank you as always, and sorry I'm late, ALL of my TH-cam notifications are messed up. ~ Chuck
Glad you dig this episode Chrysler engines are confusing they overlap and intermingle with other engine family sometimes the same displacements just totally different engines. Sorry about the delayed response =)
Hi Jay!: Another fabulous engine episode! At least they tried to stretch the tooling for the hemi block and made another pretty good engine from it! But you are right. I think Chrysler wanted to be like GM of the time, where every marque had different engines in their cars. But even they had to quit doing that by now, or they would have been out of business, too. Except for the earlier Lincoln engines, Ford pretty much used the same engines for everything. with minor updates. For example the flathead was just souped up a little when the Mercury came out. But, Ford didn't have but two or three makes until the late fifties when they tried to launch Continental and Edsel. Interestingly it was Ford that had a semi-hemi engine with their Boss 429 motor. Perhaps they borrowed the idea from the Chrysler Corporation?
Awesome information and insight thank you so much for sharing all of that definitely want to cover the 429 Semi hemi from ford Great choices by the way =)
In late WWII Ford had a dual overhead cam V-10 that I believe they intended for aircraft. It was not well received, but they did make a V-8 version for tanks. Perhaps it had hemi characteristics.
I will never understand the reluctance of domestic automakers toward the OHC valve train idea. With this design, it is very easy to produce a true hemispherical combustion chamber. Porsche did it with the original air-cooled 911 engine, and even the 1980's Ford Escort had a SOHC cam head with hemi combustion chambers. As to the "polyhead", it looks like the intake pushrods went between the bores as on a Hemi, but the exhaust went along side the bores in the valley, the way it is done in wedge engines. This saves that much money? Indeed, I would like to see the breakdown in production cost between OHV wedge, OHV hemi, and OHC hemi designs. It cannot be much different-
I'd like to hear more about the 1956 Dodge Custom Royal D-500 315 cubic inch 4 barrel V8 with 260 Horsepower compression ratio 9.25 to 1. I think this engine most likely requires premium leaded gasoline or it most likely gave much livelier performance on premium leaded gasoline.
I miss my opportunity to shoot that car this year I didn’t realize how rare it was I went to a collection where I picked four cars out I should have done that one as well because I haven’t seen another one The cars that I did from the collection were 41 packard woodie 53 packard Caribbean 1970 AMC machine 1954 mercury Monterey I’m hoping to go back there he had some incredible stuff
Jay, you have encountered the Chrysler products pushbutton transmissions. Produced from 1956 or so to 1964. Could you please do a video about them. I had a 1964 Dodge Dart station wagon with that push button transmission. I really liked it. That Dart was kind of small. I appreciated having no transmission levers on the steeting columm or floor.
It’s not in the same engine family It’s in the Chrysler A engine family but I should have mentioned it Chrysler how to go to different engine projects going at the same time and they wasn’t related This engine series was just based on the hemi block en.m.wikipedia.org/wiki/Chrysler_A_engine
great, great video. Question #1 when can get to the Chrysler A and LA engines. #2 when can you do a video on the last gen Amc engines. #3 question can you do video the on Willys Jeepster 1948 to 1951. #4 question can you do a video on the 1986 to 1987 Plymouth Turismo 2.2 ( looks like a front wheel drive dodge charger but with dual head lights not single head lights. you are doing great work and the TH-cam channel is one of the best. keep up the good work.
Small block Chevy is tomorrow I don’t have enough time to get it done today Answer to question one not sure lol I’ll try and get to at least one of those before the year is over but also want to cover some weird stuff like hudson 6 engine 308 and jet sometime Going to get to the amc engines eventually as well =) I know a guy with a jeepster it’s been on the list to do just haven’t gotten done there I’ll look for a Plymouth Turismo never heard of that car lol Glad you dig this channel it’s come a long way in a short amount of time all things considered
I liked the, 440 cubic inch V8 with the police interceptor package, which produces 375 horsepower and 480 ft-lb of torque. The monster motor could take the massive 4400-pound (1995 kg) car up to a top speed of 150 miles per hour
I recently bought an old stationary water pump from a cranberry marsh that's powered by a Chrysler 354 Hemi 🤘 The valve covers say "Chrysler Industrial" rather that "Fire Power"
I think i would pick the Windsor in the first scenario, although the Le Femme is a great looking car created for the ladies at that time, in the second I'd pick that '55 convertible 😎without hesitation!
Awesome choices =) The le femme would be a cool car as both investment and conversation piece especially with all the quirky accessories I wanna find one
Different engine family This engine family is super confusing that engine has nothing to do with the engine fan we discussed I should’ve made it more clear in the video that Plymouth only used or shared the Dodge engine in 1955 and 56 they got their own engine which also used poly heads but had nothing to do with the hemi block The hy fire 277 was in the Chrysler A family Which came out in 1955 it was offered Along side the poly/hemi block en.m.wikipedia.org/wiki/Chrysler_A_engine Also check out en.m.wikipedia.org/wiki/Polyspheric
1. '56 Belvedere 2. '55 Windsor... but I do prefer the '57 over the '56 As for the song... I don't know, but you were singing Metallica's "Until It Sleeps" at the end.
The poly head is similar to the Chevy 348 and 409 series, but without the chamber in the piston top. Also similar to the Chevy 396-454 series, Ford 351 Cleveland and Ford 429-460. All have staggered valves. The modern Hemi has no resemblance to the poly head. The modern Hemi uses dual rocker shafts as the earlier Hemi did.
Maybe someone can chime in. Pretty sure Plymouth offered a 350 poly with 2 / 4bbl's in the '57 Sport Fury. Not sure if it was an "A" block or a hemi block.
@mikew6765 - If it was a single or 2-4bbl 350 in a Plymouth , it wasn't in a '57 Fury, it would have been in a '58 Fury and the engine was nether a Poly or a Hemi , it a first year B-Block wedge engine.
Only Chrysler could come up with a line of engines that were all the same design, yet had almost zero parts interchangeability between its different divisions.
I should’ve said in the early days of the Chrysler V8 I knew I was gonna get called out on that I should’ve changed it software has been really acting up on me so I have to record the whole thing and then go back and put in all of the slides and if I decide that I want to change something it’s like the end of the world it all gets jumbled up
The horsepower ratings shown in this video are all GROSS horsepower. Today we use NET horsepower, which is determined differently. Typically you can take 20-25% off of the gross HP to get modern net HP. And that is at the crankshaft, not the tires. To put that in perspective, a Volkswagen VR6 engine from the Corrado SLC had 178 net horsepower from 170 cubic inches/2.8 liters. Compare that with the 170 net horsepower from the 331 cubic inch/5.4 liter polyhead V8....
My guess would be rock the cradle of love Billy idol, mid fifties styling for Chrysler ruined gm and Ford, they went waay ahead for 58 in worry that Chrysler would destroy again, 58 gm and Ford are bad looking cars
Chrysler was an epic engineering company back in the day now they are just a show of their former self it’s really sad to see how far Chrysler fell.. the wagoneer and grand wagoneer May bankrupt that company again with all the issue they are having but people keep buying them?? Which I can’t understand why, to each their own. The song was dress me up by Madonna I used it one other time and nobody else got it so I figured I’d try it here and see.. =)

It seems like Chevy with their small block design got a lot right and they don’t have a whole bunch of engine Families that overlap one another not saying it’s perfect because the very first year of the 265 they had oiling issues just like the Y block had oiling issues but when they got the kinks worked out it just worked

Good explanation of the Polysphere engine design. To elaborate a little, they started with the Hemi but wished to make a cheaper, simpler, lighter engine. So they kept the hemi design including the block, intake manifold etc and just changed the heads, mainly on the exhaust side. Left the intake side alone but moved the exhaust valves up and closer to the intakes, putting both exhaust and intake rockers on the same shaft and making the head narrower and lighter. This required a different combustion chamber shape, slightly smaller valves, pistons with different shaped crown and of course, different head casting. Other than the heads pistons and exhaust other parts were alike and interchangeable.
The result was very close to the hemi in performance. A 1956 Windsor would run with the hemi New Yorker or Imperial right up to 80 MPH. After that the big blockbuster pulled ahead.
First choice 1955 Dodge,(the rare Texan edition only saw 1 at a car show), the 1956 Windsor ht. Another great engine episode. Watched the Hagerty video on the Turbine cars, and the engineers left interviewed, an hour long but packed with a lot of history.. Don't forget the GMC V6 truck engines
1966 dodge charger you could get a poly 318. 1967 charger you could get a LA 318.
Even though some claim Mopar didn't release the LA 318 until 1968. We found a 1958 Plymouth wagon, and it had a 4 V carb option, for the 318 poly we had. The poly 318 ran pretty well with either carb, but the 4V carb was pretty spicy!
The 325 was also used on the 57 desoto firesweep models. They shared the chassis and much of the body with the dodges also.
great episode that explains in detail the difference between the early 50's Chrysler Hemi-head engines and the mid 50's Chrysler Polyhead engines. Anyway you put it Chrysler made good engines back then with lots of power. Looking forward to your episode on the revolutionary 1955 Chevrolet small block engine. I know its coming soon!
Definitely going to cover the small block Chevy episode I’m not entirely sure when it’s going to take a long time to put that one together there’s tons of information to go over and tons of different engine configurations because Chevy didn’t have to re-engineer their block like all the other companies did like Ford and Chrysler ford had the y block, FE, Windsor small block (I might be missing one )
Chevy did not have all those engine families they just had a small block Chevy engine family which ran from 1955 all the way up until 2003
This was another really great summary of an engine family, Jay. You're developing quite a reference library. Impressive!
Glad you dig this episode =)
A good follow-up to this episode IMO would be the MoPar "A" engine from 1955-66 ('67 in Canada).
Definitely going to cover that engine family eventually there was just so many different engine displacement and this one to make it into one huge episode there’s a lot of displacements in that family as well.
I would take the 57 Chrysler with the big fins!
Sweet =) those are cool cars
Engineer prowess was in absolute top of its game then. Dialed in. Sturdy, reliable.
Totally agree polar opposite of what that company is now
The 1955 Chrysler Windsor, in both scenarios. It was much better built than its corporate companion makes, and lacked the pushbutton transmission selectors introduced in 1956. Anyone who had a '55 Chrysler will tell you that it was a superbly-built car that gave excellent service. The '57 Chrysler corporation cars tended to rust out. The '55 Chryslers did look gimmicky, like the last iteration of a body style rather than the first, but their solidity garnered affection.
Yeah I guess Chrysler products have sort of a gimmicky Ness about them but I honestly think when I see one at a car show especially one from the mid50s they look incredible now I wasn’t around when the cars first came out I wish I was I was born too late.
Chrysler bought the Briggs body works in 1953 when Walter Briggs died. They began to produce bodies in house. Briggs built bodies for other makes, but with Chrysler as the new owner those orders ceased. They hastily began cost cutting that produced a reputation for rust. Eventually they decided upon assembling the bodies at the assembly plant - the unitized body, which produced better results. The older Briggs body Mopars were well built.
@@timothykeith1367 Thanks.
Always a pleasure to watch your videos. I'd go with the 1956 Windsor. Please do an engine history on the small block Ford 260, 289, etc. Thanks
Glad you dig this episode
Great choices that one is definitely coming so is the small block Chevy. =)
My favorite 55 56 Mopar is the 1955 Desoto Coronado. But I would be happy to have any of the six choices, even the La Femme.
I totally agree this is my favorite era of Mopar don’t get me wrong I like the big fans as well but the cars weren’t huge and 55 or 56 but still had tons of cabin space the other two Ford and Chevy have nowhere near rear leg room space as a Chrysler product one day I’m going to get in there with a tape measure and show how much more space is in a mid 50s Chevy ford and dodge product
I drive an all original turquoise and sand color 1955 Plymouth Belvedere with 24000 miles and enjoy my powerful 260 Polysphere V8. She is fast when needed. When I lift hood at car shows there are endless conversations and questions. :)
That’s awesome what do you like the most about your 55 what do you like the least I love Plymouth from that era they have so much space inside them even the two-door version I would take a 56 Plymouth anything over 57 Chevy anything I just love the styling of a 56 Plymouth also thinks Chevy ripped off the rear end design
For WYR, I'd pick the Plymouth Belvedere and the '57 Chrysler Windsor. Although the '56 looks pretty good to me, too.
Thank you for giving the background to this engine.
I've always heard more about the Hemi than the Poly. So this was an education for me.
Great choices this age and Family or version is a weird and obscure one and I had to cover it before I cover the next poly engine family Chrysler had a Lot of engines they had more engines and Ford and I thought Ford had a lot of different engine families
I’m not sure what the next engine episode is going to be I really want to do one on the Hudson twin h I like to cover some obscure ones before I get into some main stream ones but it might be the small block Chevy who knows it depends on how much time I have I’m gonna need a lot of time to put that one together
Great vid!!!!!!! 👍👍

56 Plymouth Belvedere
57 Windsor
I owned a 64 Dodge Coronet four-door sedan and it had the 318 A series engine. Or what many called the wide block engine in it. It also had the polyspherical heads just like these early polyhead engines did. However the black was different and IIRC not the hemi-style block.
The 318 and was bone stock when I bought the car used. Had a push button torque flight tranny.
Being a junior in high school, I wanted to beef it up to get more horsepower out of it.
I ended up being able to source a four-barrel manifold for it and I remember it was a for a Carter carb. I can't remember exactly which carb I ended up putting on there. It would have either been a WCFB or an AFB. I wanted to get a set of headers as well but I could just never find a set. It was a really solid well running engine with lots of power and torque. More than enough to move that Dodge sedan down the road.
The A series wide block engines never attained the Hot rod mystique of the small block Mopar series engines that followed it. Pretty hard nowadays to find any kind of replacement performance parts for the A series wide block engines. I do remember though that those were big wide engines when you open the hood of that Dodge the engine literally took up the whole engine compartment.
Great choices thank you so much for sharing all of that insight and information I greatly appreciate it =)
It's kinda funny that everyone refers to the Poly 318 as a wide block, because it's the same width block as the 318 LA. The heads are what made the Poly 318 so wide, not the block.
@@johneckert1365 as someone who's owned a 64 Dodge with the A series engine. There is a difference in the blocks of the A series engines which were made from the mid 50's through 1966. And the later LA small block engines. 273,318,340,360. Very few parts interchange between the A and LA engines. Another reason I know this is because I blew the A series wide block engine in my 64. It threw a rod, cracked a piston, and pretty much tore up the short block badly. I found out real quick while searching for a replacement that the later series LA engines commonly referred to as the Mopar small blocks were entirely different.
Now the early poly head engines did use the same block as the hemis of that era. But the heads were different being a poly design rather than the true hemi design.
@carlmontney7916 My bad, I meant to state that Poly 318 vs LA 318 blocks were the same width.
They did share quite a few parts in common. The crankshaft and camshafts were the same/interchangeable. The timing gears, timing cover, fuel pump, water pump, etc were the same. You're definitely correct though, the blocks are not the sane and don't interchange.
Many people wonder why LA engines have that weird lifter angle (rather than 90 degrees like most V8 engines. It because it uses the 318 Poly engineering. The Poly had to have that weird angle for the wonky valve train to work correctly. It was "good enough" for the LA engines, so no need to re-engineer them.
@@johneckert1365 and any mass produced item regardless of what it is if you have something that has worked you will continue to use it since you already set up to produce it.
1956 Belvedere
1956 Windsor
The Dodge Le Femme is an expensive car 😱 pretty rare ..
I always liked DeSoto The 55 DeSoto Hemi had some torque and ran strong 1 year only 😢
Fire Dome was a decent motor but pretty heavy 700 pounds ... We put them in model A fords 😂 hit the brakes on disck brakes and lift the rear of the car and Drift around backwards 😧😂 ..
Never played with poly's to much sm block Chevy is King !!!!!!!! 🤔
Great episode and
Happy Motoring ✌️🤠
Great choices =)
1955 desoto is a great looking car might be my favorite desoto
56 Belvedere is a great car as well I remember I reviewed one last year and I was really impressed with the space inside
You forgot the original version of the 318, the 277, small-block 301, and the Canadian 303. They all came out before 1958.
Different engine family It’s confusing Plymouth got that engine in 1955 midyear but it’s a different engine family that is part of the Plymouth a series
@@What.its.like. I think you mean the 56 Plymouth. And yes, a different family, but still Polyspheric.
Canadian 303 was a unique version of the Plymouth poly, meant for Canadian made Dodge and Chrysler Windsor models. Because this was the only V8 the Canadian engine foundry was equipped to make. It was borrowed for the US made 1956 Plymouth Fury because it was a direct bolt in replacement for the 270. It made the Fury quite the hot performer for the time, faster than an 283 Chev or 272 Ford.
@@mrdanforth3744 Especially if it had dual quads! 270 horses!
I wonder what the DeSoto, which was a little cheaper than a Chrysler Windsor, but more expensive than a Dodge, had in it?
I prefer the look of the ‘55 Windsor, but ‘56 would bring 12 volt electrics and push button powerflite transmission. In the end though, I’d still take the ‘55, I’m partial to it as I owned a ‘55 4 door, two tone light green and white.
How about the 413? I have a 300F with all original drive train. I believe that the letter car blocks were specially selected, maybe your research my turn up some interesting factoids.
Great research!
Definitely want to do the wedge family on here eventually Chrysler did a lot of different engine concepts just like Ford I was amazed at how many different engine families Ford had I had no idea Chrysler had more.. Not only that every year they change their engine displacement no wonder Chrysler ran out of money..
Thank you so much for adding that information what was your favorite thing that you liked about your 55 and what did you dislike the most
Glad you dig this episode =)
I remember one in a yale forklift where I worked almost 50 years ago, when I was 18 yrs old.
I abused that forklift badly, like very badly… I remember the exhaust manifolds glowing orange after holding it to the pin, for a long time, and I did that many many times, it never suffered any ill effects the three years I worked there, and still ran as good as ever when I quit.
Haha great story thank you for sharing those memories =)
WYR 1: Plymouth Belvedere (Dodge La Femme only if it actually came with all the cheesy accessaories!). WYR 2: 1957. Can't beat that peak Forward Look styling.
Ha ha ha ha yes the Dodge life femme would definitely have to have all the quirky cheesy accessories I want to cover one I have not seen one in the wild I can’t wait to go back to Classic auto Mall and get back to the glove box test and get back to the way that we used to do things don’t get me wrong I love doing cars a car shows it’s just different.. i’m not gonna be able to go back to Classic Automall until sometime next month I’m gonna try to go early November either late this month or early November I got so much stuff in the pipeline I don’t really have to go I got stuff left over for months..
Good Video.
The Poly engines are often overlooked but were a very good engine in their own right. Often overlooked is there performance potential. An interesting tidbit is that while the 1956 Chrysler 300 (354 cubic inch)354 HEMI made more HP than the top of the line 1957 354 Poly, the 354 Poly actually made more torque than the HEMI (per the factory shop manual).
It was also said the the reason for the the introduction of the Poly was that it was lighter and cheaper to produce than the HEMI. I'm sure it was cheaper, however the weight difference was pretty negligible. Both engines used the same block, intake manifolds and accessories (the exhaust manifolds don't interchange). I personally weighed a 1955 Chrysler 331 HEMI head and a 1955 301 Poly head (on the same scale). The Poly head was lighter.......by a whole 1 pound.
Awesome information thank you so much for sharing all that information and insight glad you did this video I love an engine episode Wednesdays this Wednesday push it back a little bit I’ve had a lot going on in the background which I will make my random moment tomorrow a lot of cool stuff built =)
In the early 6❤0’s I think we had a ‘55 Windsor. Occasionally on highway trips, it would die at a stop sign. I remember Dad talking about aluminum heads and vapor lock. After 5 minutes or so it would restart and we went merrily on our way. I wish I had been a camera nut when I was a kid so that I would have pictures of all the cars Dad and Grandpa and others had.
Always loved these engines! Chrysler Corp was definitely trying to find new ways to make power!
Chrysler Corporation, if you think about it did the outside box approach they first started with hemi head engines and then went poly head and then introduced the wedge
Great video!
Glad you dig this episode
It took me all day to put this one together, To the point my wife commented and said you’ve been working on that since 630 this morning it would’ve been done sooner but I had to take my daughter to gymnastics lol
I'll take all of them!
Thanks for your efforts, I really enjoy.
55 Le femme and a 55 Windsor . I completely agree with you over the wasted time,effort and money spent on all the variations of the same engine and lack of co operation between the divisions.
That always amazed me that they were able to spend that kind of money and not have any repercussions for decades later the whole turbine engine project was really cool and why they got rid of that they had some thing that would runoff of anything that was combustible, I’m not a conspiracy theorist but I honestly believe that that’s why the government has bailed out Chrysler as many times as they did because they killed that program.. if you look back at the timing of when that program met its demise just a few years later gasoline shortages started happening..
Awesome choices =)
The poly is a neat engine. It would been nice to see a revised light casting as its heavy and wide.
I think only the Chrysler 331-354-392 should have had the hemi heads. Dodge, DeSoto and Plymouth should have used a common simpler engine. The Chevy small block wedge was the best because of low costs and most weaknesses couid be overcome with aftermarket parts. The complex Mopar valve trains didn't shine as much in family cars as engineers hoped - they loved the race track.
A big block version of the Poly might have been cool.
Gmc made a v12 it was two v6 put together that shred a common crank i didn't see it unless i looked over it but i all ways throught they where neat ... Great video 👍👍👍👍
That’s awesome I did not know that definitely have to cover that engine thank you so much for that engine episode idea glad you dig this video
That's not accurate. Yes mathematically the 702 V-12 was two 351 V-6 engines put together, but that's not what it was. The V-12 did have 1 crankshaft like you mentioned, but it was also 1 block, not two V-6 blocks put together like many assume. It was a 1 piece block for V-12 only. The heads are what give people that impression, because the do use V-6 heads. So there's 4 cylinder heads and 4 valve covers. Just 1 block, 1 crankshaft, 1 camshaft, 1 oil pan, etc......
Any of the Chrysler Windsors! I'm not sure I want a car named LaFemme! 😂😂
My all time favorite is. 1957 Chrysler New Yorker, but that Windsor is just as good 😊 and more
Those cars are really sweet that’s one of my biggest regrets not doing at Hershey there was a couple 300s there I wish I would’ve done one there was some big fin Plymouth there as well but they will all be on the channel eventually =)
I have a 66 Dodge Travco Motorhome with 318-3 Heavy Duty “A” Engine this one is obscure but I really like it. Hydraulic lifters and rotating exhaust valves. Used on S-500 school bus chassis.
The only old Chrysler product I would want would be an '86 Doge Omni GLH turbo or the '87 GLHS turbo....
GREAT video!
Excellent!
Thank you glad you dig this episode =)
Outstanding presentation on this family of engines! The organization following the family line really made something complex flow more smoothly. WYR: 1955 Windsor, and 1957 Windsor. Thank you as always, and sorry I'm late, ALL of my TH-cam notifications are messed up. ~ Chuck
Glad you dig this episode Chrysler engines are confusing they overlap and intermingle with other engine family sometimes the same displacements just totally different engines.
Sorry about the delayed response
=)
Both choices...car #1.
Sweet choices =)
I do like these engines ever since I heard of em pretty powerful for there displacement and small carbs.
The valve arrangements seem to resemble the later much admired Ford Cleveland 351 set up.
Hi Jay!: Another fabulous engine episode! At least they tried to stretch the tooling for the hemi block and made another pretty good engine from it! But you are right. I think Chrysler wanted to be like GM of the time, where every marque had different engines in their cars. But even they had to quit doing that by now, or they would have been out of business, too. Except for the earlier Lincoln engines, Ford pretty much used the same engines for everything. with minor updates. For example the flathead was just souped up a little when the Mercury came out. But, Ford didn't have but two or three makes until the late fifties when they tried to launch Continental and Edsel. Interestingly it was Ford that had a semi-hemi engine with their Boss 429 motor. Perhaps they borrowed the idea from the Chrysler Corporation?
OOPS! WYR#1 Plymouth. #2 Gotta pick that LOVELY 1956 Chrysler, REALLY like that design!
Awesome information and insight thank you so much for sharing all of that definitely want to cover the 429 Semi hemi from ford
Great choices by the way =)
In late WWII Ford had a dual overhead cam V-10 that I believe they intended for aircraft. It was not well received, but they did make a V-8 version for tanks. Perhaps it had hemi characteristics.
blinded by the light manfred mann
I want the black 55 windsor
Great guess not that song or band great choices as well =)
I'll take the 1955 Chrysler Windsor(2-door). ...that's because I'll be taking delivery of one real soon.
Awesome what color is yours?
I would take a poly head over a Chevy small block any day
Agreed
55’ Windsor all day
I will never understand the reluctance of domestic automakers toward the OHC valve train idea. With this design, it is very easy to produce a true hemispherical combustion chamber. Porsche did it with the original air-cooled 911 engine, and even the 1980's Ford Escort had a SOHC cam head with hemi combustion chambers.
As to the "polyhead", it looks like the intake pushrods went between the bores as on a Hemi, but the exhaust went along side the bores in the valley, the way it is done in wedge engines. This saves that much money?
Indeed, I would like to see the breakdown in production cost between OHV wedge, OHV hemi, and OHC hemi designs. It cannot be much different-
I'd like to hear more about the 1956 Dodge Custom Royal D-500 315 cubic inch 4 barrel V8 with 260 Horsepower compression ratio 9.25 to 1. I think this engine most likely requires premium leaded gasoline or it most likely gave much livelier performance on premium leaded gasoline.
I miss my opportunity to shoot that car this year I didn’t realize how rare it was I went to a collection where I picked four cars out I should have done that one as well because I haven’t seen another one
The cars that I did from the collection were 41 packard woodie
53 packard Caribbean
1970 AMC machine
1954 mercury Monterey
I’m hoping to go back there he had some incredible stuff
You don't need to quote torque in "Newton Metres", as we never used that method to rate torque.
People have been asking about it in the comment section is the only reason it’s there to make it relevant
@@What.its.like. Must be Europeans and Asians.
Both 1955 Chrysler Windsors for me.
Sweet choices =)
All of them
Sweet =)
You really can’t go wrong with any of them
Jay, you have encountered the Chrysler products pushbutton transmissions. Produced from 1956 or so to 1964.
Could you please do a video about them.
I had a 1964 Dodge Dart station wagon with that push button transmission. I really liked it.
That Dart was kind of small.
I appreciated having no transmission levers on the steeting columm or floor.
I have,
I love push button transmissions, will definitely cover transmission eventually thank you so much for that video idea
Sad that no mention was made of Plymouth's 318 poly, bebuting in 57 with Fury
It’s not in the same engine family
It’s in the Chrysler A engine family but I should have mentioned it Chrysler how to go to different engine projects going at the same time and they wasn’t related
This engine series was just based on the hemi block
en.m.wikipedia.org/wiki/Chrysler_A_engine
great, great video. Question #1 when can get to the Chrysler A and LA engines. #2 when can you do a video on the last gen Amc engines. #3 question can you do video the on Willys Jeepster 1948 to 1951. #4 question can you do a video on the 1986 to 1987 Plymouth Turismo 2.2 ( looks like a front wheel drive dodge charger but with dual head lights not single head lights. you are doing great work and the TH-cam channel is one of the best. keep up the good work.
Small block Chevy is tomorrow I don’t have enough time to get it done today
Answer to question one not sure lol I’ll try and get to at least one of those before the year is over but also want to cover some weird stuff like hudson 6 engine 308 and jet sometime
Going to get to the amc engines eventually as well =) I know a guy with a jeepster it’s been on the list to do just haven’t gotten done there I’ll look for a Plymouth Turismo never heard of that car lol
Glad you dig this channel it’s come a long way in a short amount of time all things considered
How about doing the Pontiac V8 from 1955 to 1981!
Awesome will do that engine family =)
The GMC big block V6 series
Awesome I will definitely cover that =)
1956 Chrysler Windsor - 12 volt system
I currently have 2 56 plymouth savoys. Neither are currently road worthy.
I liked the,
440 cubic inch V8 with the police interceptor package, which produces 375 horsepower and 480 ft-lb of torque. The monster motor could take the massive 4400-pound (1995 kg) car up to a top speed of 150 miles per hour
Very cool 🤙 I just acquired a pair of 354's not sure where I'm sticking em yet
Sweet =)
I recently bought an old stationary water pump from a cranberry marsh that's powered by a Chrysler 354 Hemi 🤘
The valve covers say "Chrysler Industrial" rather that "Fire Power"
@johneckert1365 that's cool. A runner?
@@kdsboosted4954 It turns. Haven't had any free time to mess with it.
@johneckert1365 if it turns I'm sure it'll run. Mine are in parts at the moment
I think i would pick the Windsor in the first scenario, although the Le Femme is a great looking car created for the ladies at that time, in the second I'd pick that '55 convertible 😎without hesitation!
Sweet choices =)
ill take the 57 windsor or the DODGE
Sweet choices =)
WWR 1? From a collectors view, 55 Dodge. WWR 2? 57 Windsor.
Awesome choices =)
The le femme would be a cool car as both investment and conversation piece especially with all the quirky accessories I wanna find one
I know that timing chains 331 Hemi or Poly fit A or LA series engines.
Thanks 👍
Awesome information thank you so much for sharing that =)
The 56 Plymouth poly was 277 CI
Different engine family
This engine family is super confusing that engine has nothing to do with the engine fan we discussed I should’ve made it more clear in the video that Plymouth only used or shared the Dodge engine in 1955 and 56 they got their own engine which also used poly heads but had nothing to do with the hemi block
The hy fire 277 was in the Chrysler A family Which came out in 1955 it was offered Along side the poly/hemi block

Yeah that’s the tune at the end
@@What.its.like. I see... must've been an episode I missed, 'cause I think I would have recognised that one!
It was The comparison episode I don’t remember the exact years I think 1995 Ford F150 versus 2001 Ford F150
57 Windsor! How about Ford 351windsor block vs 351clebeland block from the late 60's to early 70's.
Sweet yes we will do that engine family =)
How can the 260 CID and 270 CID have the same bore and stroke?
Was the poly head engine a partial inspiration for the modern hemi engines?
The poly head is similar to the Chevy 348 and 409 series, but without the chamber in the piston top. Also similar to the Chevy 396-454 series, Ford 351 Cleveland and Ford 429-460. All have staggered valves. The modern Hemi has no resemblance to the poly head. The modern Hemi uses dual rocker shafts as the earlier Hemi did.
@@melodigrand thanks for the upgrade. I there are some folks who feel the poly was better than the LA. One wonders. Cheers
1957 windsor
Sweet choice =)
i will.pass on all of those offered. i do have my standards
Sure that the "poly" 301 Windsor wasn't just using a sleeved down 331 Hemi block with less expensive cylinder heads ?
Did you mention the 301 Poly in the 57 Plymouth?
1955,1956 Windsor.
Sweet choices =)
Maybe someone can chime in. Pretty sure Plymouth offered a 350 poly with 2 / 4bbl's in the '57 Sport Fury. Not sure if it was an "A" block or a hemi block.
That engine came later these engines were made from 1955 to 1958 Plymouth made other poly engines after this series
@mikew6765 - If it was a single or 2-4bbl 350 in a Plymouth , it wasn't in a '57 Fury, it would have been in a '58 Fury and the engine was nether a Poly or a Hemi , it a first year B-Block wedge engine.
It was the new "B" engine.
The 57 Fury was a 318 c.u. V8, 2 -4 bl carbs rated@ 290 hp
@@willobillo633 Yes indeed, and it was a Poly.
How about the GM V8 and V6 auto Diesels...?
Awesome added to the list
Only Chrysler could come up with a line of engines that were all the same design, yet had almost zero parts interchangeability between its different divisions.
Totally agree =)
"SEX FOR THE HANDICAPPED" - The Sillies 🎸🎷🎹🥁🎤
"In the early days of Chrysler"??? The early days of Chrysler were the late 1920s.
I should’ve said in the early days of the Chrysler V8 I knew I was gonna get called out on that I should’ve changed it software has been really acting up on me so I have to record the whole thing and then go back and put in all of the slides and if I decide that I want to change something it’s like the end of the world it all gets jumbled up
The horsepower ratings shown in this video are all GROSS horsepower. Today we use NET horsepower, which is determined differently. Typically you can take 20-25% off of the gross HP to get modern net HP. And that is at the crankshaft, not the tires.
To put that in perspective, a Volkswagen VR6 engine from the Corrado SLC had 178 net horsepower from 170 cubic inches/2.8 liters. Compare that with the 170 net horsepower from the 331 cubic inch/5.4 liter polyhead V8....
Thank you so much for all that information =)
55 Chrysler
56 Windsor
Not the polysphere I was looking for.
Had to cover this one first
Those early Chrysler engines of the 50's were poorly designed.Quality was a missing factor resulting in lack of power
Respectively 1951 Chrysler hemi 180 horsepower
1952 desoto hemi 160 horsepower
1953 dodge hemi 140 horsepower
Different engines these any poly head engines same block as hemi but heads completely different
putting hemi head on a 56 dodge poly heaD MOTOR
basic v8 on a 57 plymouth
My guess would be rock the cradle of love Billy idol, mid fifties styling for Chrysler ruined gm and Ford, they went waay ahead for 58 in worry that Chrysler would destroy again, 58 gm and Ford are bad looking cars
Chrysler was an epic engineering company back in the day now they are just a show of their former self it’s really sad to see how far Chrysler fell.. the wagoneer and grand wagoneer May bankrupt that company again with all the issue they are having but people keep buying them?? Which I can’t understand why, to each their own.
