Axapowell,
I have 3 individual build sheets(all from OSO members), dyno tests, and performance evaluations from HP 500 N/A upgrades. They all included a refresh of the basic short block, aftermarket cylinder heads, cam and intake change. They dynoed between 594-621 HP, at reputable shops with normal correction factors for temp, baro etc. The test for the 594 HP motor was done at the shop of Larry Meaux who is one of the best tuners/head porters in the country and also known for having one of the most conservative dynos anywhere(correction factor .98 Corr HP was actually less than observed) . The engines all have between 80 and 170 hrs at this time with no parts failure to date, including valve springs. They idle well and are turnkey. Observed speed increase ranged from 8-12 MPH.

OK...you've got my attention. How do I get my hands on the build sheets to see which combo would suit my needs and if I need any parts or machine work, who should I contact at your shop? I am only a few hours from you in Rochester!
Thanks,
Dave
