Stupid Question?

[rschultz999]

Wondering if Grand National Heads will work on a regular GM block? I am restoring an '86 c10 and when shopping for parts, I had a guy try to tell me I should put Grand National heads on it, he even (conveniently) has a pair to sell me. I don't know much about the Buick engine, but I can't image that they'd be interchangeable. Thoughts? Thanks!

Thought about this after I posted the question. The Chevy is a 4.3 and the Buick was a 3.8, so they probably wouldn't work together, right?

Completely different engines

Ya, if this guy has done work on the C10 look out. He's doesn't know anything.

The 4.3 is a chevy small block 350 minus two cylinders

But if you want to go the Chevy V6 route let me know. I know where a complete motor and parts are.
