Did you find it?
Check your casting code. It should be on the right side of the block in front of the distributor. It will be raised. This will tell you if it’s a 216 or 235, as Kevinski said. I’d be surprised a truck like that has its original engine still. It simply isn’t crusty enough! Nice truck. Yes, CDN GMCs used Chev engines on the little trucks so we Canucks don’t have to worry as much about the dreaded frame differences our southern brothers do.
By the way, whatever happened to those links that were at the top of the Engine forum and had a bunch of those decoders listed?
