Skuzz, you should be able to do that with careful detective work. Mr. P body (Jim of Central Virginia Machine Service) can make dished pistons out of certain forged TRW pieces. They are thick enough at the crown to be modified, and they are not that expensive, but I think you need to find the pistons. If I were building a hypo motor for myself, I would install dished pistons for sure. I almost never drive my '65 GTO because I have to run race gas. A real buzz killer. With dished pistons, you can make great power and run "cheap" pump gas. Good luck.
