Poly 318 Questions

members here might can answer all your questions, but you might also try the FBBO guys. probably larger number of people there that have tried all the various things with the poly, probably.
the guys that do the " Chrysler power" mag, they seem to be up to their armpits in poly things! I have read about them years back, than can make decent power, but last time I read, it costs more to get than what you could get out of a 340, 360 for same or loess $$.
lets face it, some of us Mopars guys don't always follow the "cookie cutter" theory. if a person can afford it, there are guys that love to make more power out of the poly, especially if they have an early car that came with it originally.
maybe some other members can chime in on the power they can make.
