A few engine questions

Yeah, if there weren`t the differences, we would all be running 273`s bored .500 over.:toothy10: You can probably pick up about 6 cubic inches with a .030 over bore on a 318. The secret is to pick good parts, good oiling, close and consistent tolerances put together in a sterile environment. Pick a good valve train and you can get it to wind high while staying together. :read2:There`s a lot of info right here at FABO that can help you build a crazy 318. Go for it!
