I'm all out of thoughts. Can someone help me ID this engine?

[DocAtDuq]

Hi all,

ive been trying to identify the engine I'm my sport fury and I'm all out of thoughts. I can't seem to locate the block stamp. Maybe I'm looking in the wrong place. Anyways I though it was a 383 originally due to 383 being stamped on the intake manifold. But the carb is 2 barrel.

Then I stumbled across this article where they talk about the unique valve covers which seem to match mine exactly. Can anyone help me? I don't have very detailed pictures on hand.

Thanks
jordan

318 poly

it should br embossed on the driver's side of the block...from appearance...looks like a 318...all small blocks have distributors in the rear...the old hemi's..392 and down also BUT you cant't mistake the heads...all BB had distributor in front so not a 383 for sure...or 361...or 440...426

I believe these "poly 318" engines are actually a different family than the LA engine family that's so common in late 60s to 70s Mopars. Some people call them big block 318s.

The early small blocks are 'A' engines.....

Thanks guys.

Not sure where to go from here. I'm assuming that because the 318 is smaller it makes it a less desirable engine? Kind of clueless here as to what it does for value too considering hagerty doesn't even have that listed.

Thanks again

Edit: Just a precursor, I would never ever sell this car. It has too much sentimental value to me. I have essentially the same car as that in the article, but mine has vacuum assist brakes I believe.

I learned something. I didn't know that.

At least it's not a 6 cylinder car. The cool thing is these cars are easily upgraded to bigger cube motors.

A lot of guys are building up the poly 318 and more hi-po parts are becoming available....good luck.:headbang:

As someone pointed out, the early smallblocks are "A" style engines. The "LA" family of engines are "LATER A", or LA style smallblock engines.

Poly 318 , looks like a wide block . Gary pavlovich is the man google yahoo 318 poly group lot of nice people and lots of info and help.

 

[patrick66]

LA = Light "A", as these were nearly 50 lbs lighter than the "A" Poly-head 318.

There are quite a few parts that interchange between the two engines, plus there is still at least one aftermarket aluminum four-barrel intake yet available for the Poly.

 

[A383Wing]

66 was the last year for the poly 318 engine in the US.....but dual exhaust on it and a 4bbl carb and it will wake it up pretty good....also, keep the valves adjusted to specs

 

[DocAtDuq]

I wanted to thank you all for the wealth of information I've received from you all.
While id love to drop a 383 or 426 max wedge in it the car holds more sentimental value like I stated in the past. The previous owner was the son of the original owners and every mile and oil change is documented (mainly because the son was a plymouth mechanic and one time).

But what I'm gathering here is that I can freshen this engine up and bring more life into her via a 4 barrel, new intake manifold, and dual exhausts. It's good to know I can get more power out of her.

Thanks again

DocAtDug, The block stamp you are looking for is located on the front/top of the block at # 1 cylinder just below the head. Your engine is an A-318 Polyspherical head engine and appears to be original to the car. For 1963 the block stamp would start with T318.

If you are interested in learning more about this engine, parts available etc. I am the owner/moderator of a Yahoo Group, The 318 Poly List, having 740 members this engine design is much alive and becoming more popular every day.

My '63 Fury runs a 359 cu.in. Poly stroker making 392hp, one of the best engines I've ever had...Nick T.

 

[DocAtDuq]

Thanks nick,

could you recommend where to start with upgrades? I was going to get a 4 barrel carb, dual exhaust and better headers.

i checked out your website last night and it was a wealth of information! Thanks for that.

Those are some wicked valve covers! Where on earth did you find them?

 

[furyus63]

IhathAfury, These valve covers were made by Craig Fountain in Australia. The last contact info I had was; [email protected].

the 318 poly is a semi hemi engine produced buy plymouth and was use to 66 in the US and 67 IN Canada and with the right parts breathes way better than any other wedge motor chrysler ever made besides the hemi

Just a few photos, I had a 64 Belvedere Poly with a Weiand intake, 600 Edelbrock, and TTI headers and exhaust. Just those few changes made a big improvement.I'm sorry I ever let it go. Check out Chrysler Power Magazine,they have intakes, cams,valve covers and more for the Poly.
