I finally got delivery of my '56 GMC and here is the ID # that is located to the left of the dizzy. Can anyone tell me if this is a 235 chevrolet engine?
Thanks,

Post a pic of the actual engine.

Here are 2 they sent me before I had the truck.
I can take more if necessary.
Thanks,

On the straight 6 engines casting #, it is on the back on the passenger side of the block, hidden or almost hidden by the starter, or along the middle bottom of the block, possibly hidden by an motor mount.
The casting# should be 6 to 9 digits long.

Hmmm, I was told that it was to the left of the dizzy where I found that one in the first pic. Don't know if my old body can get the digital to take pics in those locations you mentioned or not but I'll see what I can do. I may end up with the trial and error method on the valve cover gasket but I probably need more accurate info if I stick an electronic ignition in it, huh? The plug wires are horrible and need changing so I probably need to come up with a plan. I"ve never had any experience with an electronic ignition so I'll need to find some tutorials and get familiar with them.

Here's what i have on the # you posted Em, (F = Flint / 3 = March/ 09 = 9th day of the month and A = 235 standard engine). maybe someone else can shead some more light on this but this is what i come up with on your #s.

Thanks Cole, guess I need to find the other casting number, eh?

[wretched ratchet]

OK, I have done my homework and here's what I've got. Thank God for the Digital Camera

The Engine Serial # which I originally posted here
F309A
Now I have the

Head Code on manifold side
3836848
GM12

Block Casting Code below the dizzy hole to the right
3764478

This was on the side of the head between 2&3
B23 848
850

The Block Date Casting Code was hard to get but
here's what it appears to be:
CON 4 ?088

I may have to remove the solenoid to get that last number if it becomes necessary to be able to identify.

[eloc431962]

could the # be 376447(6) instead of 376447(8) if so you have a 235 from the year 56-62 235 engine casting # 3764476 .

I'm gonna pull the valve cover off and get that last number and then start ordering and wrenching.

Thanks Cole,

Just for grins, here's the last two numbers
(man, the valve cover gasket was toast -
no wonder there was oil blow by all over)

Hey Man, I'm glad you got your truck safe and sound. Seems to me you've go a Chevy engine in your GMC. While I'm not sure about, I believe the GMC small truck six was a 270. Appears you've got a Chevy 235 3764478(6). Here's a link to a service manual;

It might be a Canadian built GMC....They had Chevy engines in them....If it is, it might say "Made in Canada" on the firewall tag
