I have a 79 Gmc Heavy half that I purchased a year ago from my father,I want to start fixing it up and redoing it. I want to put new headers and exhaust on the truck but the problem is,he tells me the engine is a 72' 400 sb I dont know what kind of car that came out of and all I have is some numbers on the block if i give them to someone can they tell me the year and model it came out of? I also need to know if the lug is 5-5 offset because I am buying some rims and I havent got any clue if the offset is right. I really appreciate any help.
