Yes a Chevy engine will work, but you probably will give half of the members on this board vapor lock if you pursue that option. Please define "blew up." You may find that even if the block/crank was destroyed there may be enough accessories on the old engine to justify purchasing another Pontiac 350/400 block. Also in the long run I believe putting in a Chevy will devalue the car enough that if you ever go to resale you would be better off to put back in a Pontiac Engine. BTW, what part of Virginia are you from?
