Possible engine for Cab 13 C15a

[Jordan Baker]

Hi everyone

Would this engine be possible for fitting into a Cab 13 C15a. Im not exactly sure what kind it is other then its a GM engine. Its in the remains of my Grandfather's 1974 GMC Sierra pickup. It looks very similar to the GM 261 and I know they would work in a CMP.

After speaking to my Grandfather about it he said it had very few miles on it as the truck was mostly used around the farm or for short runs around the Hamilton area. He stopped driving it about 15 years ago as the body adnf rame had complety rusted out. The best part is that its mine free of charge. All that I have to do is get it out and battle the many yellow jackets that have called the body home.

If the engine is a no go for the CMP would one out of an International Harvester truck fit. Looking at it through a hole between the hood and fender it looks very similar to the Chevy straight six. I will post photos of it in the next few days.

Anyway here are the photos of the GM engine.
