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.

[@What.its.like.]

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 =)

[@randyrobey5643]

@@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.)

Precisely why I LOVE Mopar stuff! I bought my 67 Coronet when I was 20 in 2000, mainly because it was old, different and LOUD. My good friend couldn't keep up with it so I got it for $600. Little did I know that 318 was NOT the 318 I knew of. The kid before my buddy owned it swapped and older engine in. Didn't take long between working on it and getting so many questions and wrong guesses at the gas station and I was in love. I know they're not the power house, easy to build, parts everywhere sort of power plant...which is WHY I love it. Not once has a Chevy 350 piqued my interest. They're great motors obviously...but farthest from unique or rare as could be. Some engines I dream of building one day are a 413 long ram, early hemi, and old big block nailhead, 427 Ford, Ford flathead to name a few.

[@mrdanforth3744]

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.

[@Vegaswill714]

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.

[@garymckee8857]

I owned several of the poly 318 and as long as the oil was changed they were very dependable engines.

[@What.its.like.]

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

[@Vegaswill714]

@@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!

[@What.its.like.]

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 =)

[@davidpowell3347]

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.

[@bparksiii6171]

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!

[@8176morgan]

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!

[@What.its.like.]

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

The 325 was also used on the 57 desoto firesweep models. They shared the chassis and much of the body with the dodges also.

[@johneckert1365]

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......

[@the_car_guy5915]

Polys are so underrated. I obtained a 65 Dodge block that I'm pretty sure will accept LA heads. Gonna turn it into a 392 stroker and use big valve J heads. I stuck an LA cam in and it fits identical to the poly one. The heads bolt right on and pushrods all line up with no interference.

[@carlmontney7916]

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 =)

[@johneckert1365]

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.

[@carlmontney7916]

@@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.

[@johneckert1365]

@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.

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.

[@timothykeith1367]

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.

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.

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.

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.

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?

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 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?

[@melodigrand]

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.

[@Gary-yo4rs]

@@melodigrand thanks for the upgrade. I there are some folks who feel the poly was better than the LA. One wonders. Cheers

[@garymckee8857]

Sad that no mention was made of Plymouth's 318 poly, bebuting in 57 with Fury

[@What.its.like.]

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

[@I.Live4oldcars.prospecting]

Did you mention the 301 Poly in the 57 Plymouth?

[@Flies2FLL]

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-

[@unknownuser16335]

I currently have 2 56 plymouth savoys. Neither are currently road worthy.

[@mikew6765]

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.

[@What.its.like.]

That engine came later these engines were made from 1955 to 1958 Plymouth made other poly engines after this series

[@martinsuter3531]

@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.

[@jamesbosworth4191]

It was the new "B" engine.

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

1956 Chrysler Windsor - 12 volt system

[@RodgerMudd]

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

The problem was they were big, heavy. And a later 350 Chevy 375hp solid lifter motor, would spank them all.

They were cool and have a distinctive sound tho I got to go for a ride in a dual ghia with a 318 poly it would move and sounded awesome

[@Flies2FLL]

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....
