- Steve Dulcich and David Freiburger are prepping to rebuild the 318ci small-block V8 in the off-road 1970 Dodge Challenger after the engine got destroyed in Roadkill Garage episode 17. While they were plucking the engine out they got to talking about the history of the LA-series small-block Mopar engines and the various changes that were made throughout the production of the engine platform.

I really like it when David and Steve geek out about engines, there's so much information that they've just absorbed over the years
Sorry to be so off topic but does someone know of a trick to get back into an instagram account??
I was stupid lost the login password. I appreciate any tricks you can offer me!
@Joshua Mohammed Instablaster ;)
@Dominik Payton Thanks so much for your reply. I got to the site through google and im trying it out atm.
Seems to take quite some time so I will get back to you later with my results.
@Dominik Payton It worked and I now got access to my account again. Im so happy:D
Thank you so much, you really help me out!
@Joshua Mohammed no problem :)
Freiburger in a boat:
"It's got the sand."
"The what?"
"The Saaaaaaand."
Perfect video. The 340 LA engine is one of the best. Mopars with this small bock has great performance and especially excellent handling.
I really like listening to these guys. A boatload of knowledge and knowhow when it comes to allthings Mopar in general and small blocks in particular. No multimillion dollar studios packed with state of the art equipment, just hand tools, beers, and the cars. Great stuff indeed!👍 👍
I was suprised to hear them bash on the magnum motor.... : ( the built magnum motor in my jeep zj runs 12 .6 all day long in 4wheel drive. I love it.
There just old and hate change
yea, sorry but the magnums is so much better than the LA, especially the 80s smog engines.
Lot of engine for small frame
Love to see a video of the jeep
I owned the small block six pack and big block six pack cars. All of them were 1970s. The only issue with the 2300 series Holley carburetors was that they tended to dry out in the winter after several seasons, because we didn't drive those vehicles in the winter time. So the old gaskets would dry out and you needed to rebuild them which really is quite simple. Probably one of the main issues that plagued the vacuum secondary carburetors oh, was that they would get perforations in the rubber diaphragm, and then wouldn't open the end carburetors like they should. This led to a lot of us making Progressive linkage setups to do away with the vacuum operated end carburetors. I really liked the performance of the six pack set up on both the big Blocks & the small blocks. However when I went to the 440 + 6, a very serious change in torque and Power. For instance, I owned a 1970 Factory V code 440 + 6 GTX. The only work I did to this engine, was fully grooved rod and main bearings, which I purchased Michigan 77 bearings, melling high-volume oil pump, 484 lift hydraulic cam with sealed power anti pump up lifters, and tuned equal length headers and collectors length that matched my build. 3.73 gears and a 4-speed trans and this car with 10.5 compression ran 11.78 in the quarter mile. So if you plug the figures in for the weight of this particular type of car, and the minor changes I made to the engine, the horsepower figure had to be fairly decent. I can tell you this for sure, there are faster cars around today sure, but back in the day there was nothing much different between the 426 Hemi and the 440 + 6. The torque out of the big block six pack car is amazing
Please do a cheap 318 power build
agreed. theres a ton of 318s out there, i bet folks would love to see how to squeak an extra hundred horses out of it on the cheap
I kept the original 318 in my 1974 Satellite I restored about 15 years ago. It only had 67k on it and did not want a race car. Just something with pep. I had the heads rebuilt and ran the rest with after market and rebuilt it myself. Cam, intake, carb, headers, stall converter, shift kit. My only high priced parts were new Edelbrock carb and a custom DUI ignition. I doubled the HP from 150 to close to 300 I left the original 3.11 gears ( I think) I was getting 18mpg and because of the high gears my power band was over 40 mph.
George Ward I do agree with this as well, I personally have an 85 Dodge D150 pickup with a 318 that's mostly stock but the engine has had a fresh rebuild over 19k ago. I don't wanna go out to the strip but I want it to have some power to it and really get down the road, plus I'm a teenager that loves to push the throttle on old square bodies lol nothing like a street truck man
Use 308 heads from an 87-91 or Magnum heads with AMC lifters. If not doing an inexpensive stroker, use a 273 Crank. It's lighter and fits. There are a few lesser known, low budget, old school ways of getting more power from the 318.
If you google "The Mopar Muscle Truck Blew Up - Roadkill Extra", starting at around 2.25 they describe a pretty nice 318 power build. Not necessarily "cheap" but you could improvise.
Great stuff as always, guys! I love it when you guys dig into the history of different engines and teach us what is what! I've always been a big block Mopar guy, my first car was an E body, a 1974 Dodge Challenger, it had a 440. I sold it (like an idiot) and bought a 1968 Dodge Dart, it got the 440 out of the Challenger. I completely agree with you guys, a small block is acceptable in an A body or E body but not in the B body! Any ways, thanks for all the great info and another great video!
These vids are cool...feel like it's three of us standing around a project, trading stories. I daily drive a 5.9 Grand Cherokee so it's like I get a daily dose of LA Chrysler nostalgia...
It's a blast, I love it. I spent 6 months searching for the right one and I put a lot of work into making it my own--both mechanically and cosmetically. It's my first Mopar and I've developed a whole new respect for LA blocks. I also have a 2002 4.0 TJ, which I bought new and have 319k on it...I've developed a similar respect for the old AMC sixes. Keep up all the good work, David--love the empire you guys have created!
The 5.9 Jeep is a Magnum, not LA. Different engines.
Every episode is great. Thanks motor trend for keeping this alive.
I love this stuff..Takes me back to all the discussions we used to have in the garage while wrenchin on these old Mopars.
I have a 71 satellite with a 318, gotta love Dulcich standing up for the little people.
Uncle Tony's garage (on you tube) has a 72 coronet (I believe) warmed over stock cast piston 318, some minor port work and an overdrive truck 4 speed with 4.10 gears that they plan to spray...Made a couple shots today on the street and it sounded really good!
Oh trust me I been through his channel a time or 2. Love what he's done to his 318.
I love these cuz it’s like when my friends and I are just chilling out and just talking about cars and engines and what we wanna do to what we own and stuff like that
I would love to just be in the room while these guys talk cars. This is automotive passion right here.
every Mopar guy should dream about having a 340 Dart. my first car when I was 16 with a 74 Scamp slant 6. that should get a chuckle from anybody but I loved that car and it didn't take long before I changed it over to a 318. when I switched the K member it came out of a 340 Dart GT but the car was trashed. big block darts only belong on the drag strip anybody who wants an awesome car needs a small block A body
big block darts only belong on the strip? scared of a big block dart eating your 340 on the street?
@@hirkimerwilberfart2413 340vs big block, build both the same and in the same vehicle, big block will win every time. it's physics. sorry.
@@hirkimerwilberfart2413 boat anchor? LMFAO. nice 20-30k 340, with a 4000rpm converter, and 4.88 gears. now do the same to the big block. what dominates top fuel? BIG BLOCK MOPAR HEMI.
92 was the first year. i had a dakota with the 318. that truck flew i loved it.
Ahhhh, Mopar engine talk. *sips coffee
Literally how I'm starting my day... 👍
While I consider myself a car guy, I don't know a ton of mechanical specs. This is almost as hard to follow as a lawyer talking to an accountant lol
Steve Oswald it gets easier to understand with time
When you say 'fixing it' you mean install motorhome 440 right?
A No Dulcich (rightfully) wants to build a really mad 318
Dburger62 I hope so! I really want some ideas for my 318
Dburger62 I know. Just having a little fun.
FUCK you need to make more videos on TH-cam unsubscribing because all I have is dirt every day
Nathan rip And All you get from ded is teasers! I'm not unsubscribing but it is extremely frustrating. I did however discontinue my mod because it really wasn't worth it. I pay over$60 a year for Motortrend magazine. They should toss this shit in for free for that In my opinion.
Would you guys do a Roadkill Extra episode on the 318 A poly engine?
For money
273s had the intake bolt angle and bolt size for 64-65 then it changed for 66. In 64 the 273 only came with a 2bbl carb making the 1965 cast iron 4bbl intake a one year only part. Took me forever to find one for my 1964 Dart. The heads are different in 64-65 too.
first vehicle out of high school was a 92 Dakota, with an efi 318 (just pre magnum) I loved that truck
Pulled the 11.7 :1 360 from my Duster yesterday. Gonna dump the compression so I can drive it on pump gas. What fun cause it will need a new cam so a new tune. Gonna repaint it to. Next summer will be better than this lousy summer was no matter what the insane world does. A 73 Duster will live on with it's 4th tune and 4th paint job since I bought it. And I'm a Ford guy. Love me some Mopar I do. Momma drove nothing but when I was a kid. She had a 67 Valiant, 69 Dart, 70 Dart (Panther pink), a 72 Charger, and then...a used one, a 70 440 mag RT Challenger convertible Plum purple. Mom liked Mopars.
That's why I love my LS lol. I have just a touch higher compression and I can drive around on 87 if I'm not super hard on it.
When I first bought my house, my neighbor across the street had a 70 Roadrunner that he was rebuilding, but he didn't know ANYTHING about the engine or transmission, he was more of a body guy. The ice breaker between him and I was when he was working on his car one day in the garage I told him that I would help him put the engine and transmission back in (383 with the 4 speed, best combination imo) so I came back about a month later and it took us 2 hours to get the package in the car, mounts bolted in, and running. He had issues with that car from the get. It ran great, but he had rust issues that he was dealing with and he wanted to paint it. Eventually, he got sick of it and sold it to a local guy for $1500 and never told me or I would've bought it, painted it, and finished it correctly. I'm still kicking myself in the ass over that.
Why is 383 4 speed the best combination to you? I get the manual trans but other than nostalgia the 383 is a 440 with all the weight with no power. Mildly built small block will out perform without the big block weight. I'm just curious.
@@hirkimerwilberfart2413 383 is less valued and less rare and less powerful than a 440 car. That was my point
I loved my 340. Great engine.
roadkill "extra" should be sponsored by coronas.
They won't do it. Good idea!
Let Mike drink Coronas.
Isaiah M I offered David some Corona merch before, never heard back.
They're not allowed to have alcohol on the show anymore, since Dave bit the dust in the shop that one time.
Legal said 'No'.
Corona and flip flops. Lol
I did the 273 iron rocker arm thing back in the 80s. I had a solid cam in a 318 with 340 heads
"It has the sand"
The what? The sand. It's the new thing.
i can listen to these guys talk cars all day
glad you finally made a video on 318ci. I have the magnum and if been having nothing but trouble
Odd. Usually those motors would be reliable, but the rest of the vehicle it's in falls appart.
You didn't say anything about the cast versus forged crankshafts and harmonic balancers.You have to be careful to not mix them when doing a build.
Also torque convertors - neutral balance vs. weighted.
Are you talking about the difference between internally and externally balanced crankshaft?
My brother prefers B and RB, I prefer LA. I probably have to many projects. Daily driver is a 99 1500 extendedcab, 360 4x4. Also have an '80 Powerwagon 150, 360, 4 spd, 4 bbl, 4" lift, and 35" mud tires. Have most of the parts to convert to 1 ton running gear. My old high school project truck. Was built in my dads garage as cheap as we could. 57 D100 with a 2spd push button automatic. Back in the early 80's we picked up a '69 Plymouth for parts. Used the torsion bar front clip, wiring, 8 3/4 diff. Later on we rebuilt a 340 to replace the worn out 318, rebuilt the 727, and added 2500 stall convertor. I've owned a handful of Ramchargers, '67 Dart GT, several pick ups with the LA. The 57 was going to be mounted on a 98 Dakota frame for modern suspension and drive train. My dad passed away in May, so I'm just going to strip her down, and go through everything since it's been parked for over 15 years. Shit I just realized I'm damn near writing a novel. My one and only big block car was a '69 Coronet R/T. That Holley double pumper would empty that fuel tank in a little over a 1/2 hour, in spirited city driving.
Many years ago I had a 70 Duster with a 340 "6pack" engine. However, the guy I bought it from rebuilt the engine for use in a sprint car and later put it in the Duster for drag racing. The best ET he got was 11.37 and 137 mph in the quarter (he kept the slip). That car was a riot and dangerous! Two brothers I knew each had 440 GTXs and the 3 of us raced one day. I ate them for lunch! Unfortunately, a women ran a stop sign and I tee-boned her pushing the engine and drive train back. Sold it for parts and bought an Aspen station wagon to haul the wife and son around.
The three factors that made the Mopar small block cool (not in order) is, the ability to find a good big block for cheap, the availability of good cylinder heads that don't need offset rocker arms (ie, the W heads, if you couldn't afford those, you had to seek out early 360 heads with the 340 ports or the late 1980's cop car 318 heads) and stroker kits. Now you can affordably take a 318 to 350 cid with a 360 crank cut by speed o motive or 392 cid, and have a head that won't choke it. Or you can take your 360 to 400+ cid, and have a power to weight ratio that makes a 440 not worth it unless you stroke that thing out another 30 cubes or more.
The early 318, that was used from 1956 to 1966, was also known as the "poly head" 318. For 1967, a "LA" version of the 318 was introduced.
That is correct. The "poly head" 318 was also sometimes known as the "wide block" 318.
It was made from 56 to 66 in the US and until 67 in Canada and the LA block bottom end is pretty much interchangeable even camshaft just needs some slight milling heads are different
Those old poly’s also get referred to as a “semi-hemi” sometimes
I actually like roadkill extra and roadkill garage, I'm just to lazy to get the subscription 😂
For me it's not lazy. The guys just need to realize, no one pays for content anymore. And so often, Roadkill actually sucks.
Jeff Parris it’s only 5$ a month and it’s really easy to access on their app, I could just torrent all this stuff but it’s too much work
An old friend I've lost in time once told me that they could listen to me talk all day about certain topics. Now I finally know what they meant as I feel the same way about Freiburger regarding automotive. I've probably said this before but how the hell does he know so much intricate history of cars & shit?!
I am with you on the B body needing a big block. I am in the process of putting a low mile 85 318 in my 66 Plymouth Belvedere daily driver which currently has the Polysphere 318. Looks so sad in the engine bay
I’m happy to see mainstream give Mopar attention!!!!
The A had polyspherical combustion chambers and the valves were like a hemi or a BB chevy where the LA had wedge combustion chambers and the valves were side by side
Damn dulchic back at it with the mopars again
Also the 273 differ from the rest of the family in that the timing marks on the balancer are on the opposite side. I ran into that problem on the 65 barracuda that im working on. It now has a 71 340 in it but had to use the 273 water pump to work with the radiator and now my timing marks and needle are on opposite sides.
Early LA 318's and 340's had the timing marks on the same side as the early 273's. Changed in 70 or so when they changed from the short iron water pump to the long aluminum one. So it's a date thing, not a 273-specific thing.
Also, you can put the 273 balancer and timing cover on the 340. Or just bolt the 273 timing tab to the 340 front cover and run the 273 balancer. Then you'll have the timing marks where you can see them.
Intake on 273 was the same for only 64-65 they switched in 66. I’m currently building a 273 cast date 64
i knew they where wrong when they said 68
the LA/Magnum engine was used until 2002. The "Power Tech 4.7" replaced it in 2003. Along with the almight hemi...or so it wants to be. The 318 hit the frames in 1967. 273 did run til 69. Listen to Mopar Man Dulcich
The LA 318 lasted through 1991, the Magnum through 2002.
The LA 360 made it through 1992, and was last used in 2003.
The 4.7 replaced the 318/360 only in the Dakota/Durango, and the Grand Cherokee. It replaced the 318 in pickups after 2002, and the 360 in pickups after 2003.
The 3.6 V6 replaced the 4.7 in all vehicles noted beginning in 2011.
Just today I took the valve covers off the LA Smog 318 in my Gran Fury to replace the factory ones. 30 year old gaskets and no oil leaks, Chrysler sure had some good stuff. Not like that Italian-Canadian designed and built SRT today.
Genuine Chrylser engineering and parts are invaluable. New valve covers gaskets and an oil pan gasket and then the engine will be ready for some good oil. At 31 years, with 24,240 miles, you can't beat a good engine.
Now I know the bore and stroke of the 318.
The Italians have nothing whatsoever to do with Mopar V8's.
The 5.7 Hemi, like the Viper V-10, shares its origination with the 360 Magnum. Overall dimensions and bore spacing for the 5.7 came from the 5.9.
Continuous improvements made to the 3G Hemi V8s have eliminated all valvetrain and timing chain issues, making the engines not only very powerful, but very durable.
I have a 1987 5.9 360 with edlbrock Magnum heads and 1.7 edl- rockers and a 572 edlbrock cam with double roller timing Chain with stock crank and Pistons double spring valve springs edl, and a edl performer intake and a edl 750cfm carb with 3 edl fuel pumps 57gph and bullit proofed 727a trans with Dana 44 rear with billit axle shafts #gotta love mopar
You didn't mention they're also available in Dodge motorhomes.
So was the poly headed 318
Talking about the 318, I had two '66 coronets both with a big block 318s.
The odd pattern on the intake was 64-65 almost bolting strait down . In 1966 the 340 intake would bolt on a 273,I know I did it and ran 14.6 with a 500 cfm.2bll. street able.
They didn't mention it,...but yes, someone does make a three two barrel throttle body ( with intake manifold, and linkage) for the 5.2 and 5.9 magnum small blocks.
Now you can build a modern version of the 340 six-pack!
This is cool stuff for a Brit! Good motor info in condensed form!
when you guys came to tucson, it seemed dulsich wasnt having a good time. i hope he comes back next year. he was a cool guy. thanks for the videos
Cheers fellow Tucsonian
they came out in 1967... LA stands for Light A, the initial motor was released in 56 and was heavier..
So true
They did not come out in 67 the barracuda was released in 64 and had the 273 as an option
The production of the (a) engine and (la) engine over lapped 64-67
But the la absolutely was around in 64
The engine released in 56 is the (a) engine which they built a 277, 301, 303, 313, 318 and 326
Really want to confuse the non mopar guys go to the parts house and order parts for a mopar 361
I think the a meant used in a bodies
Whoa, was that a dig at the General Mayhem's "upgrade"? Don't know about anyone else, but I loved it the way it was.
I have a 1992 Dodge power ram 250 4x4 with a 360 LA,
It's an old "state" truck. It never fails when getting parts for the engine I end up with something for the magnum engine. This is my first Dodge, I've only had it 3 years, and have been trying to figure out the differences between the 360LA and the 360 magnum. This gave some good info. If anyone else could add to this, it would be greatly appreciated.
Thank you, I really enjoy your program.
I would like to hear about the Plymouth Weslake small block. Would it be feasible in this time for reproduction?
I believe the V6 transmissions will bolt to a 318 as that motor was an option on those early trucks starting in 1991. Not sure if it will work on early flat face 90' and earlier daks. This swap can be easily simple depending how far you go. Schumacher creative services makes all the engine mounts you'll need. Depending where your 318 cam from (car vs truck), you'll need a truck pan to clear the frame. You will also likely need to Upgrade the fuel pump with a regulator to get the right pressure. Now, it gets more complex here...all your guages and cm instrumentation was set for v6....I went carb and 1971 340, so I didn't need to worry about any of that stuff, but it certainly might throw codes on you. If you go carb, go MSD ready to run distributor, 3 wires and boom. While I'm thinking of it, go 360 rather than 318 if it's smiles per gallon your after. Also, don't use a 360 pan on that 318, it won't work. Anyways, there is lots more to consider, axle strong enough? Rear gears for performance and on and on. Best luck to you! Chris
Talking about small blocks in B bodies, I recall working @ Andy Mannarino's Total Automotive in Detroit. We built a 390+ inch 340 for a customer, John Amo for his 64 Barracuda tube chassis car. With a four barrel carb (4500?) it made like 730 HP on our dyno! (But a switch to alcohol & old style fuel injection the number dropped to 700) Well, back up about 20+ years my buddy Al had bought the Silver Bullet' from Jimmy Addison! I was there the day he gave him $5000.00 for it complete. A 67 GTX that had been acid dipped with fiberglass trunk lid, doors and complete front end & with a tunnel rammed 496 " (Pro Sock?) Hemi it went 10.30's as a "street Car" I remember Addison telling us the engine made 735HP! So I always wondered what ET's could've been achieved with that small block in that car?! Keith
yeah ..id like to see a 318 build w/ stock bottom end and both after market an stock heads..carbureted and injection options would be a plus
Waste of money. Buy a 318 or 360 magnum, drop er in and go.
My grandpa has a 72 duster with a 340. Sounds beautiful.
I have an old Dakota with a magnum in it. Still runs good, minimal maintenance on the engine. 238,000 miles. I would take the engine out and do some other project with it but not much after market support for Dodge stuff.
If! All things being equal costwise, how does the 360 stack up against the 350 small block Chevy?
Seems the chevy got better mileage?
Both seemed pretty reliable. What’s the difference?
why do some people think I'm going to hell for putting a 440 in a 96 Ram
Rusty Stuff Don't worry about all the moron's! I'd gladly go to hell to see your 440 conversion!
farmvideos .net it's going to happen some people might call it archaic others cobbled but I will call it in mine
You are, for wasting a good 440. Just kidding. :)
And you'll still have 12 valves run circles around it.
12 valves made 400 ft lbs stock. yes, you can upgrade them, but put a turbo on the 440 too and see what happens....bye bye...plus you want be paying more than the trucks value when you have to repair the diesel.
You guys have a very informative channel here keep up the great work
Can we just have a show of you to talking like this I could watch this for hours
Have any tips on a building a 350hp 318? Can it be done with iron heads?
Please do a old school 426 Hemi build that would be freaking awesome :-)
These videos might actually be worth going over the website! (Just kidding) great video though
I have the same stance on what bodies should have which engines.
The reason the 273 was still around in 1968 and 1969, is because the 318 was not available with manual transmission. In 1967 there was supposed to be a new high performance 331 engine with a hydraulic camshaft and the same size valves as the 273. The performance was so disappointing that it was scratched. The 331 had a 4.00" bore and the 1968 340 increased this to 4.04", got Chevy size valves and intake ports. The 1967 and early 1968 318 engine blocks are heavy enough to be bored to 4.00" as the castings were originally meant for the 331.
I swapped a low miles Tquad 340 into my 70 RR 440-6 "back in" about 73. Excellent. You are talking about a "350 Chevelle" Got 17.5 mpg with no effort, and would stay with a 383 RR
you guys should do a roadkill version of overhaulin.... and help me work on my 360 in my ramcharger lol. Its so hard to find mechanics like you guys who actually know what they are doing with old mopar.
what about the first gen v10 that was in the ram trucks. Wasn't that designed off the LA series?
hey dave my first car was a 1971 challenger 340 slapstick, 3.23 rear 5 spoke magnum wheels! bought it for 1000.00!
The biggest problem I have found is the converter pilot hole in the crank. It was small in the early engines and bigger in the later ones.
I had a 79 Chrysler 300 LE with the 360 LA motor equipped with the E58 Police Interceptor heads. It would handle the similar year Stingrays pretty easily. Freiburger clarify your comment about the LA motors versus the newer Hemis.
Thanks for the reply.
Now I want to see Dulcich's 71 Satellite!! I bet that thing revs like a banshee!!
Yes, Plymouth trucks. I have the 2 wheel drive Plymouth Trailduster hardtop convertible.
Hey Steve, I need a 318 for my 1986 Ram D-150 Custom Royale. I think you have one "lying around" somewhere on the ranch!
Would it be harder to make power out of the near magnum rather the Mopar 318? Let’s say around 350-400hp nothing crazy just curious
Is it cheaper to go .030 over if the sand has worn it most of the way there already?
SBF guy, but I appreciate the good stuff here. 340 is an excellent motor. What was the bore and stroke of the Trans Am racing (limited to 5.0 L) 'Cuda of the early seventies?
Same bore as the 340 (4.04), shorter 2.96 stroke (vs. 3.31).
the Magnum engines are great engines, extremely reliable if maintained
Love me some Dave and Steve.
whats the general consensus on small blocks in trucks?
I have always been a fan of the A engine. The Polysphere 318. The block of the A engine is 95% the same as the LA. The cranks and rods all have the same dimensions. The heads up are the biggest difference. They are a semi hemi design, much like the Ford Boss 429, except the Poly actually came first. They were a VERY good design for the time in fact it has been argued that the poly heads were a more efficient design than the LA head that replaced them. Another thing that has been argued about the poly heads, is that when engineers at Chrysler and Dodge realized the potential of them they saw them as direct small block competition with the hemi. And ultimately that may be what was the demise of the poly head 318.
As a Chevy guy I must admit I love the late 60's n all the 70's Mopar MC's. But that discussion right there boys n girls was some serious Mopar Poo Poo😊
So much knowledge.
Upto 1967 the smallblock 318 was only available in the "polly" wide block version. The LA took over in 67 after
What he said about a late model Hemi in a 1970s Mopar goes the same for a LS engine in a 1960-70s Pontiac.
Does anyone know what that intake and carbs are? I can see holly on the side of the carb
I was trying to think of something clever to say "how I wish you were pontiac guys" but the backdrop makes me think of my grandpa?
is the magnum 318 a Good motor mine is a 93 i want to put a 4bbl carboraitor on it what would be the best carboraitor for that motor i bleave it's got 9.1 compression so what would be the best intake and carboraitor to get the most horsepower please tell me
Wow didn't know in Canada we had the A or poly 318 till 67 68 was our first year of the LA 318 or low angle block when from a 90 degree v angle to a 60 degree v angle and all the internal parts fit from la to a
Ok, I just love you guys. Lol. You have my dream job. I wish I knew as much as you both do.
yes do story on plymouth trucks i got a 75 Plymouth trailduster originally had a 400 big block now has a 60 over 360 . like my small blocks.
any insight on dulcich saying the late LA's had hydraulic rollers? I know a guy with a 90 318 and he said it had flat tappet. guy was a diesel mechanic with a 1st gen ram. when the magnum switched over from the LA in late 91' they introduced better flowing heads 1.9 intake and 1.60 something for exhaust. magnum heads also have pedestal mounted rockers. the magnum also has a stronger bottom end from mother herself. the heads has flimsy casting, EQ from Australia makes a aluminum version with 2.12 intake and 1.92 exhaust valves and with much better casting. I recommend EQ for anyone looking to bump up their HP numbers and power band on a magnum or LA engine. EQ makes them for both engines as well.
Just a suggestion so I can actually see and watch how about collaboration between David and Steve with Mark Worman? That would be interesting to say the least
these guys are mopar wizards that can fly
the ending I found the most interesting, the hate towards the modern hemi. is it the cost or lack of aftermarket support or something else?
T1000AX the head bolts on modern hemis are torqued to the point to where the bold head pops off, so you need to drill them out, it weld an apparatus to them to remove the heads.
i don't know. they plucked my nerve though. i have a 6.1 in a 68 super bee. it will run circles around you typical 440 body and get twice the mpg. hell, a stock 5.7 would hurt the feelings of a typical 440. not sure where he was at with that comment
Steev Don what are even talking about?
its easier and cheaper to get power from a smallblock mopar.
i doubt that alex.
