Thanks, everyone, for the help. I knew the sub-frames were the same, I just didn't know if the holes drilled in Pontiac sub-frames were in different locations than the holes drilled in Chevy sub-frames. I'm near Orlando. My car is apparently a Sprint OHC car, but I'm only seeking a one barrel-carbureted engine.
Thanks again, and if you know of a Florida club that can help with an engine, please send a message. Any similar info. pertaining to North Carolina clubs would also be helpful.
