Any suggestions on how many miles I should put on the motor before I dyno? The block was honed/re-ringed w/ all new bearings, gaskets and seals. The head got port and polished, lapped in valves and new valve seals. Installed a VF stage 2 as wellI've put about 600 miles on it so far. I'm going to switch to synthetic @ 1500 miles. Ok to dyno then or will waiting longer free up a few more hp? Trying to hit 250whp.
