Guys
I need some help. I was told my truck had a Poly 318 but I cannot verify with the casting number that I found. I know it is a poly but need some help.
The casting number I found is 2284370.
Any help is greatly appreciated.
Thanks

Re: Poly 318? Maybe!!
What year is your truck? The easiest way to tell is by the valve covers - if the bottom edge is scalloped, it's a poly; smooth, it's the later LA-318.

Also, poly valve covers are held on with 2 bolts, one each end, thru the top. LA are held on with several, around the edges.

Guys
Yes it is a poly 318. The valve covers are scalloped and have the bolts on the ends.
I am more wondering if it actually a 318 but I cannot find the casting number on any references.

The year and cu.in. will be stamped on the front left cylinder rail right where the head meets the block. There is a machined surface there with a stamped engine id on it.
A casting number will not be specific to year only a range of years.
