Thanks all. I had put the engine in a s10 4x4 balzer about 10 years ago. It has been sitting at my work for a number of years since I stopped using it. Since Hurricane katrina I have a 69 vette and a 69 camaro to rebuild, and I was looking to maybe use this one in one of them if it had a roller cam. I tried looking for the #'s on the pad but it's pretty tight in there and would need to remove to much . Thanks. robert
