I remember reading something a few years ago that said to stay away from '77 blocks because the "castings are thin." I dont know if this info was correct or not. Has anyone heard of this?
I wouldn't believe anything you hear about "thin castings". Unless you're pushing 700 horses, I don't think it will matter that much anyway. I have a '77 truck block in my car right now. If you're worried about block stability, you could always get a main stud girdle.
