I would have liked to see how lifters from Comp Cams compared to the others.

Never buy Chinese crap lifters

I just asked this same question to Elgin, since I had purchased their hydraulic flat tappers and 292 cam and then got real nervous of catastrophic failure if the quality was china inferior! I sent an email to their tech dept. wanting more info about their lifters- here’s their reply! “ Hi David, Thank you for your inquiry. Elgin lifters are OEM, made by Eaton & Delphi. The flat tappets are from the same Eaton factory that makes them for OEM assembly lines. What ever inventory the OEM's don't use at the end of each week is made available to the aftermarket through Elgin. The HL-1817 are coming from the GM Engine Assembly Complex in Mexico. These have the lifter body cast and machined in North America. We sell them because they are the only lifters that we will cover with our warranty.

Are they actually made in the USA, or just assembled, and made in Mexico? Are there reports of lifter failures being made about these? I would much prefere to know in advance of blowing up my engine! Your honesty is paramount, as I will still continue to buy your products! Are these issues due to poor quality metal (China metal), or are your lifters built from quality USA steel? Thank you in advance for any and ALL info you can provide! (Also I am fully aware of proper break in procedures- varying rpm’s from 2000 to 2500, and at least 20 minutes to 30 minutes- never let it idle during break in, use break in specific oil high zddp oil and change the oil and filter, right after break in with another high zddp quality oil and filter) thanks! -- This e-mail was sent from a contact form on Elgin Industries (www.elginind.com)” made me feel much better after getting that reply! ps, my lifters do not have a parting line, and look like a solid body with the recessed middle section like the pic of the Summit ones above. Even the numbers are similar, indicating the most likely other companies are also buying left over stock assembly parts to rebrand, and sell. ‘there’s a bunch of guessing going on these days, so when you get the info straight from the (reputable) company, you have to hope for the best going forward!

I bought a nice original '58 Plymouth Plaza sedan a few years ago. Not being a MOPAR guy, I knew nothing about 50s Plymouth engines. I have been nothing but impressed with the 318 two barrel engine. It is reliable and powerful, a lot of fun to drive!

The Poly 318 is an awesome engine. Thankyou for your factual and sensible video.

Had a set of Hughes lifters presenting the same issue of scratches on the face. I won’t be using them. Will use Isky cam and lifter set

Chrysler shot themselves in the ass when they dropped this motor. Bad bad move.

Great video and trip down memory lane. I had a poly-318 Coronet in high school and it was very reliable, economical, and took a helluva beating, but kept on ticking (literally).

Great video with great content. I have a 66 Plymouth fury convertible that has the 318 A block. Could change it out but I like the idea of keeping it original to the car. Part of the fun is finding parts for it and making it run well enough to keep up with the big blocks. Please keep up the great and informative videos . 👍

Thanks for the review and - Phew, Paypal can be a pal sometimes. IDK if it's the same Hughes as for Transmissions, but I do have the deep finned cast aluminum pan with drain plug. Looks the part in box. I am considering Rhoads for street use 383 NA TBI but unsure of their regular or V-Pro with 288/298 444/466 lift cam.

It happened to me I got 4 ousand miles from my fake timkens 2006 gmc 1500

Thanks

Where does the 241 cid from 1955 fit in?

I owned an Australian assembled right hand drive 1959 Desoto Firesweep, it would have been a 1958 equivalent in US and Canada, it was fitted with a 361 cu block that if I remember correctly developed a claimed 309 bhp, it had a push button torqueflite auto, air and steer, however the air was not factory but a very neat aftermarket wide slim underdash unit. A light green with dark green top and those beautiful 3 bullet tail lights on each fin, the Desoto had the best looking front grille and rear tail styling of the forward look Chryslers IMHO.

Great video. One of the interesting things that I noticed is that some poly engines have a much more pronounced sawtooth shape to the valve covers than others. I wonder if the big sawtooth poly's are the semi-hemi engines or if there is some other explanation.

The B block was introduced in 1958 at 350 cubic inches.... In 59 grew to 361.

Thanks a million for covering this series!

Who says the Internet cant be informative? I onow 340 wnd 340 6 bbl and 440 also 5440 6 bbl a hemi owner addition ally 413 ramcharger. Thid video provided more info than all thoe mopar guys. Todays engines are all about technology and fuel efficiency Back then romp and stop gastest car wins. My old nova SS installed 406 SB lunati racing cam it would turn completely sideways from dead stop get 13 on the highway ,17 in town. I long fit yhe day of hemi charger 440 6pk sioer bee 440 corner RT Even 340 duster

I’m an old dude and former automotive machinist who loves engines and this was a really well done video. 👍🏼👍🏼

Great video. Timken hub for my Silverado is $180 everywhere but Ebay, where it's $80. Sure enough, pictures in the auction show all of the details you warn against here.

I have a 66 Travco with original Poly 318-3. This engine pulls the coach quite well. I have the hydraulic lifters and the 4V carburetor. . I can make the case that the A engine cools better because of the mass of the heads. Long live the Poly. Great video BTW.

The LA 273 could be had in the '65 Plymouth Valiant and Barracuda. That's probably the earliest use of that engine. Also, I owned two vehicles that had the A-318. A '62 Dodge Power Wagon 4x4 and a "65 Belvedere I inherited from my parents. Both were high mileage and both used a little oil, but didn't break down. Excellent, informative video I might add!

I have a 57 dodge one ton dually with what I thought was a 315ci. poly. Is it a 313? I really like it and feel like it's a rare find and hope to get it restored. Dodge all the way!!!!

Had a '66 Belvedere 318 in '82 The interior was trashed and someone primered it brown looked like with a paint brush. It was hideous I tried to blow it up and burnt up 2 tires. I filled it hose water trying to freeze crack it. Grandad replaced the tires and freeze plug 6 months before died. I inherited his '77 Ford F150 351M and gave the car to my cousin. Wish I still had both today

The Poly came back in the modern era as the 4.7 SOHC V8. The principle was the same. I will say this......the Poly has one of the best sounds ever produced by a V8. There's a stroker on CZcams that will make you smile.

These poly engines are really cool. Not sure how many people know that the modern 4.7L sohc engine has valve placement that looks almost identical to these old poly heads. I wish Chrysler would have kept with this design. Were they the first to bring this canted valve arrangement to the market out of the big three? Will Poly heads bolt onto an LA block?

We had a 59 Plymouth wagon with the 318 in it and you couldn’t keep main bearings in it. It ran pretty good and was pretty quick but the front sump oil pickup starved the oil pump under hard acceleration.

One data point. I have a 1956 Plymouth with a 277 / Powerflight. Decades ago the crankshaft broke under another persons ownership and the car was sidelined. From what I understand, broken cranks on the 277 were an issue.

Our family had a slew of 318's. '59 Suburban with a Torqueflite and a gas heater, a '60 Dart Pioneer w/ Powerflite, a '64 Savoy w/ Torqueflite, a '64 330 w/ Torqueflite, and a '63 440 w/ Torqueflite that I did change the intake to a 4bbl.

I have one of these rebuilt sitting on a stand in my conex box. Even picked up a dual carb intake for it. garage art!

Its a crying shame that Chrysler didn't develop this engine further performance development 😮

My dad bought a new 59 Plymouth Savoy with a poly 318 & automatic push button transmission … motor & transmission were bullet proof reliable !!!!

👍👍 Many thanx.

My grandfather worked for Chrysler in Windsor his first job was the engine plant not sure what year he started but it was in the 50's for sure when he retired he worked in the big van plant on Pillette Road he also worked in the main plant back in the 70's when they were building the Cordoba's and the Lil Red Express trucks.

Did I miss the bit on the 273 LA or Low Deck A engine ?

My dad bought a 55 4 door savoy 6 cylinder, bought a 56 4 door for parts that had a V8, it's a poly with dual points and I believe a 2 barrel or single barrel 🤷 has spark but could never get the poly V8 to fire. My dad passed in 2016, we still have the 55 savoy and the poly V8 and transmission is still bolted to it. Always had plans of putting the V8 into the good car, only thing savable from the parts car was motor, trans and glass, hood and trunk and doors

i have a polyhead 318 in my 1965 Coronet 440 ragtop i love it for it's uniqueness and dependability would get it rebuilt if anything would happen to her

They forgot to mention the self driving 1958 model named Christine.

My 66 Dodge Cornette 500 2 door had the 318 poly.

I put an old 318poly into my buddy's ram charger. It has a ton of wear and tear on it but smoking a little, a quart or quart and a half a week of oil and he kept it awhile

It would have been nice to see further development done on the poly heads.

There's enough quality information in the video. Makes an old Mopar man like me appreciate my automotive choice even more. Subbed instantly!

I put a 66 or 67 poly 318 into my 70 fargo. Got a big older 4 speed truck transmission and. Bell housing. It bolted together except for one main bell housing bolt that didnt line up. Ran it for a decade like that. Was a great combination.

He forgot the 325 dodge.

Timing Chains fit 318, and the early Chrysler Hemi

Would like to see some flow bench data on the poly vs LA.

Nice video, but two things... The term "Semi Hemi" didn't come around until the middle 60's and it was applied to Big Block Chevy engines who were then competing against the 426 Hemi. Chrysler only referred to the Poly's as "single rocker shaft engines" when they were in production. As for them being cheaper, yes the quality of the components was top notch, but they had fewer parts and less metal overall, Chrysler was able to save on the second set of shafts, the rocker shaft stands and their machining, the pushrod tubes etc. They were by no means "cheap" engines, just cheaper than the Hemi.

great content, I worked at mound rd engine and other big 3 plants as an outside contractor doing concrete form work. I look foward to more of your videos, thank you
