I know small blocks rev, but if in my case the engine has been built and been on the dyno...
My 318/390 made it's most torque and H.P. less than 5000 RPM, so doesn't make sense to rev the crap out of it unless it keeps making power! Just my 2 cents.I shift at 5000
If you're making the most power at 5000 why wouldn't you rev it past that so when you shift it drops back into your power band instead of below it or at the bottom of it. Just a question.
