[QUOTE="bull3441, post: 11224265, member: 104648"] i asked the same question to Michael @L&M. his answer was , i stay with 93 oct than i'd only see about a 15whp increase bumping the compression to 9.5:1 vs stock CR. he felt i shouldn't go over 17psi on pump gas whether i used his Diamond or Manley 2618 pistons. race gas was a different story obviously. yesterday i put a $10k deposit down for a motor build. as of tonight i think i'm gonna pull the plug and go with L&M instead. i wanted to stay local in the invent an issue were come up, but L&M has built a lot of modular motors and know what works on the GT500. just my 2 cents.
