With a set of flat top pistons for a 307 Chevy V8 and some cylinder head work, a 250 can be a pretty good performer. One of my Vo-Tech school students built one that way for his Chevy Nova and he and a buddy with a Firebird with the Pontiac 350 in it couldn't outrun each other. They would race to school about 20 miles every morning, and whomever got into the lead early on could stay there all the way.
