For anybody looking to do an intake like this for the street, put a balance tube between the two manifolds under the base plates, it will help smooth out idle & off idle. A coolant line connected to them will also prevent carb icing.
Should make the intake leave the block and go down at a 40-50 degree angle and come back up for long runners and balance pipes between the two front and rear and as well as each set front and rear. Could get a couple three feet more runner length and also the exhaust. Could be worth the extra length and cost , low end power would work
@@dennisford2000 Doing an intake like you suggest will create fuel fallout that will hurt low to mid range on one of these old engines. I have a 384 Packard straight 8 & my friend races a highly modified Buick 320 at Bonneville.
Random blocks of wood for an engine stand? Bubble-gum welded custom intake and exhaust? Cardboard 'battery box'? This is my kind of dude - I feel like we'd get along just great :)
You still haven't. I'm old enough to have rebuilt one of these from the ground up, blueprinting and all, and they sound a lot more even and buzzy, like an angry hive of bees. This specimen, though well painted, suffers from what most of them did... the block is weak in the middle and the head can't hold it together without a "belly band", a later era mod, so the head gasket blows between cyls four and five, much like a model "A" betwen cyls 2 and 3. I did a LOT of flatheads in my teens and twenties, including a small family of ford flathead v8s for a collector who wanted them restored to factory original function and appearance, and he even had a NOS gasket set, all good. I put a '32, a '34 and a '36 on stands for the guy, in full demo mode. They range from the original 65 hp version to the larger bore and stroked version at about 95 hp, and in 1939 was replaced by a 239 v8 "Y" block.
@WeaponOfChoice not necessarily. Well yes they do have to rotate through the same 720° of rotation oh, I didn't know if it was going to sound like a conventional American V8 or if it was going to sound like a flat plane V8 like a Ferrari. Flat plane V8 sound like Hondas on steroids.
@@thatcarguy1UZ Oh, gosh, I can’t walk past this… First. The ‘American V8’ thing is quite dumb. Mercedes, BMW, Audi, Jaguar, Rolls-Royce, Bentley, Lancia, Toyota, Nissan, Kia and many more car makers produced/produce only cross-plane V8 for their daily drivers. Second. If a V8 has an even firing order it doesn’t matter if the crank is cross- or flat-plain. The exhaust matters. There are numerous vids on the TH-cam in which cross-plain V8s with 8 in 1 equal length headers scream like Hondas on steroids.
@@aleksandrnestrato ok, I’ve thought on how to respond for 15-20 minutes. Which is forever for me… I’ve had driven studebaker v8’s to fords. And many Chevy v8’s in between. The ls motors, because they are so cheap and powerful seem to be my favorite. Never been a fan of European cars because of the cost, not wealthy. But I’ve read of the new corvette with the flat plane v8, idles rougher but has more top end power.
The fire department I worked for had 2 1953 Packard Henney ambulances. Both had the Ultra Matic transmission and dual factory carburetors and were a dream to drive and work in. They handled very well on the road too.
Sounds like a 1950s hot rod. Very cool. Got my 48 Packard running after sitting sence the early 70s and it sounded like a sewing machine, ran per-r-r-fect!
@@oldnick4707 I'm sure they had main bearings.. I didn't know how many. In 1954 it had 9. During the war Packard made engines for the P 51. By 1948 I think most engines had main bearings. I think the 30s manufacturers charged a lot on engines. 50s engines were a lot better.
@@Motorhead_Mark, Not sure, but done well, babbitt bearings can be awfully slick. You line-bore and face the block and caps as an assembly and it comes out really straight if done correctly.
Nice to hear the old Packard 327 again . My brother had one in a 1948 convertible Victoria . Lots of torque and very smooth . Excellent long distance cruiser with overdrive allowing around 11 m.p.g. on the highway .
Honestly, since I heard inline 8 engines were pretty much extinct I didn't think there would be a TH-cam video of an actual inline 8 that is still around but I guess I was wrong. And since this is a video of an actual inline 8 that is still around, I am pleased since I think this engine is pretty cool.
They are really cool engines. I have been looking for an affordable possibly basket case engine for a pre-war Boattail racer that I will be building after I start my TH-cam channel with a Morgan style racer build.
I've thought many times about building my own intake and exhaust manifolds for a inline engine with dual carbs. But I have never thought about doing it to a flathead, especailly and straight eight. Pretty neat. Thanks for the video.
Packard, "Ask The Man Who Owns One!" Also, Packard manufactured some V-12 Merlins under license from Rolls Royce, back in the early '40s for the P-51C and D Mustangs during WWII. Also, way back in the 1930s, they had advertisements showing a man balancing a Quarter on the hood of a Packard with the old straight 8, as it was idling.
Back in the mid-Sixties one of my high School friends inherited grandmother's 1952 Packard Clipper. That straight eight was smooth like a turbine and that old Packard was damn' fast too.
Time wise, I broke the travel record between my homestown's Park and the county seat Garage, that has stood for forty years. A infamous cousion driving a straight Packard had made the run of record in his Straight Packard that had some modificaitions for road racing. My stock 1979 280ZX sniped time in the flat straights and big curves to bring the Win back to the Family. Crazy Cousin Windel drove like a madman it was said. Full power and whereever the car steerder, it was kept a full power and coacked im as well could be do to not loose not speed. He ran wide of the course sometimes but a full speed.
I have a local cam grinder I use, after I start building this car I’ll pop the head, grind the valves and re ring the pistons. And have the cam reground. I’d like to put a sn89 supercharger on it too after I get the bugs worked out.
Back in the early 1980's I bought a 1954 Packard Clipper with this engine. The car only had 76,000 miles on the odometer. The engine spewed out plumes of BLUE SMOKE everywhere! I bought the car for the body and interior which were in great shape. I actually got a ticket for "excessive smoke." I never found out why it smoked so badly. I soon sold the car and made a few bucks.
Thanks for commenting. This one smokes too but I have no idea how long it’s sat. It’s in a roadster now behind a radiator (see my other videos). I hope to run it with coolant this week and see if it clears. Stay tuned!
Beautiful! I always liked the straight eights of Buick, Pontiac, and Chrysler cars in the '50s. Tough, rock solid, and durable - like this Packard. I think Buick was the only one with Overhead valves, the others were flatheads. Chrysler also offered a straight marine engine before the HEMI marine engines. They performed quite well for the time.
@@CreatorCade, If he's going to 'Hot rod' it, but not 'high boy it', then any chassis he gets he'll have to cut chop and channel anyway, so he might as well scratch build a chassis out of tube stock. This gives you a hell of a lot of freedom though. Rear end choice, type of rear suspension, tires, brakes all around, the front end will have to extend out the front I would think? Could be really cool like a Jay Leno mobile though!
My dad said he and my uncle learned to braze at 15/16 yrs old , early 1950s. Solely to cut cast iron intakes and make them dual and triple carb.Then later to weld and make exausts. On the streets of Chicago mid 1950's, Dad could change a set of blown transmission seals in 30 minutes with hand tools and a jack, 2 wheels on the curb. Then race some more till the seals blew again - rinse repeat. He said he bought them by the dozen. He also had a spark plug in the exhaust pipes, and a solenoid valve for fuel. and headlights in the rear wheel wells for smoke show and flamethrower exhaust 1955-58 !!. He said it was common, South side and north shore kids ...back then
Great sounding classic. A helpful hint on those welds(I am sure your still learning) turn the heat down and use a back purge tube. You will thank me later. If you can watch some welding vids. I recommend welding tricksandtips
Good job on bringing this very old engine back to life. Call me crazy but I thought it sounded a bit like one of those straight six Detroit Diesels with no exhaust. I’m sure it’s nothing like that in person, and it sure doesn’t sound like a V8. I wish you the best of luck in this cool project of yours.
Thank you very much for the kind words and encouragement. I’m almost done with the first stage of my dads studebaker and the Chevy nova. I’ll be switching those cars locations in about a month. I can lay out the components and frame for this packard roadster build then. Stay tuned!
I have a stock 37 Packard with the 282 CI eight, you may consider making intake and exhaust manifolds for a Stock setup but using a modern two barrel Carburetor because origional manifolds are hard to find and needed. It does not need to be fancy for people like me who actually drive their cars.
I just put a new coil on it, other was bad. It runs really good now. I posted a few new videos. Next it to have a radiator and let it run long enough to burn off all the oil I pumped into the spark plug holes. It is a 327 ci
Very nice, I’m fixing up an old 52 Pontiac 8, thing is very tired and begging for a full overhaul. What have you done to it so far besides that beautiful dual carb setup?
Thanks for the comment! Not much with the engine. I have a video up where I’m bending steel for the body for it. And I do have another video of this engine running with a new coil, runs better!
ohh baby you got the 327 version. I have teh 288 and i luv it. been wanting to make some kind of custom intake with a bigger carb some day. are those bug carbs?
Nice work. Love straight 8s and 6s. The spark plug layout belies their offset in the cylinders. How far are they from the cylinder walls and are the heads domed much in their location.? BTW...that engine seems to idle at about 200 rpms?
I think the plugs are over the valves. In this video the engine had a bad coil. I have another video where it’s running much better. I’m working on it tomorrow. Thanks for commenting
Sorry I missed your more specific question. It was made with a 3/8 steel plate for the base. I drilled holes for the round ports. Then two different size mandrel bends. The cross linkage has a treaded rod inside a 1/2” tube. That was the real trick
I see a lot of blow by coming out of the lifter plate where the road draft tube would be and it is timed with what sounds like a dead cyl. not firing can you let me know on that ,And that is a Great old Engine ...Thanks
Mark, could you measure the length of the Packard 8 compared to a traditional smallblock? Er I guess just a measurement of the Packard 8 would do. I'm curious the kind of real-estate that engine takes up.
It’s 40” from bellhousing surface to front of harmonic balancer. I just put up a short yesterday. Runs great with the new electronic ignition. Little Smokey though, I am hoping if it runs for an hour or two it will stop smoking, otherwise I have to at least re ring it
Yes it does seem to have blow by, it’s sat for quite some time and it’s only run for a minute or two. I’ve had engines do this before, just gotta run them longer. I plan to put this in a 1925 model t bucket that I’ll build next year
Just a cheap electric fuel pump off Amazon. Just enough to test fire it for a minute. I’ve only run the engine for 2-3 minutes total. I know it needs tuning
It is running, but I see a lot of combustion gases getting by the rings, and hear what may be a leaking exhaust valve. Remember--fix first, paint later.
One carburetor throat per intake port doesn't seem ideal for a straight 8 with this firing order. The paired cylinders draw on the intake port one right after the other and I believe the fuel distribution between them will be uneven with the pulsing flow. This thought is what kept me from doing 4 SU carbs on a friend's 327 Packard. It would be interesting to try it and study the results with a pair of oxygen sensors.
Someone asked last week, possibly you. If a few people want this I would set up a limited production run. They would likely cost 2500-3500 each. They take quite a bit of work
It’s a flathead, meaning not overhead valve. I have another engine like it that I would like to put a turbo or supercharger on it. That would be how to get 400 hp out of a flathead straight 8
@@Motorhead_Mark That's what I figure out. At first I was looking at it thinking, wait, all ports exit the same side? Then I realized it was a flathead.
I'm a little concerned about the pulses og puff, coming from the breather plate, beneath the inlet manifold....they look a little too strong for just blowby.....!
It’s on my engine stand now. All re ringed an valves lapped. New reground cam and a coat of red paint. I have newer videos with electronic ignition and it was running awesome. Building a car for it too, see my last short with the sheet metal and wood floor
For anybody looking to do an intake like this for the street, put a balance tube between the two manifolds under the base plates, it will help smooth out idle & off idle. A coolant line connected to them will also prevent carb icing.

I can't help but wonder what a long-tube equal length header would sound like on this old fossil of mechanical craftsmanship.
Comments should give it a rest. It's early on, he's just cranked it up for a moment or 2. Let him tune & so forth for awhile.
Thank you!!!
And the echo out on the lake.Tahoe would be great
I dont know why but when I hear this engine I think of a tractor in a rainy day doing some hard work on a field
Mounting Weber downdrafts on a flathead is like putting big Hoosier tyres on a Yugo 45.

So smooth you can balance a roll of nickels
A small equalizer tube between the carbs would help low speed.
Okay, this is my first complex intake build. Hopefully next year it will be in a chassis and I can run it longer and tune it. I appreciate the advice
Looks like it has some healthy amount of blowby coming from the crankcase vent below the header....
Whatcha putting it in? Love this stuff.
Webers for the win!
I like that T5. I'd like to see how you set up the adapter.
I did just put a video up on that subject. You can comment if you have any questions

Great project!! What bellhousing is that? I also bolted a T5 behind a 327. I used a GM bellhousing, yours looks much cleaner

How are those carbs pulling fuel uphill from that petrol can?
Just a cheap electric fuel pump off Amazon. Just enough to test fire it for a minute. I’ve only run the engine for 2-3 minutes total. I know it needs tuning
It sounds absolutely V8-ish!
I have another video with the new electric ignition. Runs so much better
We come a long way refining tolences since this motor was made.
timing or points are off, The Packard straight 8 is a very smooth running with no shaking around at idle
I just wanted to see if it would run. Gotta put it in a car with a radiator to tune it. Hopefully later this year
I just got one running after sitting in a trashed Packard 200 for forty years...next step unknown...
Awesome at least you saw the car. Mine probably ran last when I was in my 30’s
It is running, but I see a lot of combustion gases getting by the rings, and hear what may be a leaking exhaust valve. Remember--fix first, paint later.
Oh dear. Hope someone showed him where the idle speed screws are...
Nice job Mark, what kind of transmission do you have bolted up to that Packard?
It’s a t5 out of ford mustang. Maybe I’ll make a video on how I made the adapter out of 3/4” aluminum plate
One carburetor throat per intake port doesn't seem ideal for a straight 8 with this firing order. The paired cylinders draw on the intake port one right after the other and I believe the fuel distribution between them will be uneven with the pulsing flow. This thought is what kept me from doing 4 SU carbs on a friend's 327 Packard. It would be interesting to try it and study the results with a pair of oxygen sensors.
Firing order 1 6 2 5 8 3 7 4. Yes I like the afr gauge idea, maybe later this year that engine will be in a chassis
@@Motorhead_Mark
the su carbs will work fine when others wont
far superior than yank rubbish
I have a Jeep 4.0 and would love to put a carburetor on it it’s so restricted with the fuel injection I know that it’s got more power
Well fuel injection is pretty nice, like everyone says, you have to go through the whole thing. Cam compression, exhaust gears…
It sounds like a V8 with a misfire haha
Not sure if I asked before but could I get a carburetor setup like? From you or your fabricator?
Someone asked last week, possibly you. If a few people want this I would set up a limited production run. They would likely cost 2500-3500 each. They take quite a bit of work
@@Motorhead_Mark ok let me get my coin together and follow up with you if that's ok.
@@louiscollier6577 absolutely, I would create a website, with my contact info so things could get discussed further
The last 2 cylinders get the worst scavenging unfortunately
how did you.convert this to air cooled?
It’s not. I’ll be running it behind a radiator this week
Why not an equal length exhaust manifold? Sounds nice tbo
I’m going to put it in a model t roadster. The exhaust will sweep past the cowl
The straight 8 is a strange animal. It’s sounds like a V8 but also doesn’t.
I was thinking the same thing I kept hearing a dead zone in the idle.
Is there any way to build it to make over 400 hp ?
It’s a flathead, meaning not overhead valve. I have another engine like it that I would like to put a turbo or supercharger on it. That would be how to get 400 hp out of a flathead straight 8
Ah, flathead. I couldn't figure out why the intake and exhaust were entering/exiting the same side.
Valves are in the block, just above the camshaft. No rocker arms on flatheads.
@@Motorhead_Mark That's what I figure out. At first I was looking at it thinking, wait, all ports exit the same side? Then I realized it was a flathead.
How'd you get DCO carbs to work like DGV's 🧐
They are down draft carbs if that’s what you’re asking
@@Motorhead_Mark Yeah that's what I'm asking. At a glance they look like side draft carbs.
What size is this one?
It’s a 327 made in 1948
Ok
Did anyone build a V16 based off this engine and head design?
Cadillac had a v16 flathead. Packard had a v12, I think it was used in pt boats in ww2. I think it was ohv, but I’ve never taken one apart
Are those Webers? I think it's a first to put Weber carbs on a Packard straight 8! great custom work.
Thanks, I found the carbs on eBay for about 100 each. IDE 44’s
@@Motorhead_Mark ,are they IDE or IDF???
@@jorgecardozo7684 it says idf on eBay
What’s the compression ratio
Flatheads in general are pretty low since the valves are in the block on the side of the piston, probably 7-8 to one
I think the webers are wasted there.I would a depression carb like the Stromberg or two Holleys 2300.These Webers usually work better on higher rpm
Ok thanks for the advice, I do hope to have the cam reground and have it live around 3-4K though. Just a test fire to see if everything worked
Rings must not be seated yet?
I don’t think so, it’s been sitting.
I'm a little concerned about the pulses og puff, coming from the breather plate, beneath the inlet manifold....they look a little too strong for just blowby.....!
Transmission fluid pumped into the cylinders will do that. Hasn’t run in decades
It's got quite a bit if blowby. Rings valve guides not right.
It’s on my engine stand now. All re ringed an valves lapped. New reground cam and a coat of red paint. I have newer videos with electronic ignition and it was running awesome. Building a car for it too, see my last short with the sheet metal and wood floor
The engine is painted green.
It is green energy, yes?
Sure! I like that. I saw a packard v12 painted green, so I copped that. It was 100 percent rust color when I found it.
@@Motorhead_Mark I enjoyed the video.
Thanks for posting it, and sharing the great sound!
