This is a long shot but here it goes. My stage 1 is numbers matching execpt the engine and it was replaced with one from a 74 buick. I am looking for the orignal engine and heads for it. its a 70 gs stage 1 so it is an ss coded block and numbers 0h321555. For help the car was from Ottumwa, IA. The orginal owner name was wesley frazier. So if you find this block let me know of if you know about any history of this car or remember it that would help me out a lot. For help, the car is and was gold with a brown interior.
