What RPM range do you want to use the power?The rear end will have to stay 3.08 unless at some point I swap to a 700r4. I’ve considered adding a trutrac but feel it’s not worth opening the rear end until I’m ready to do gears and full rebuild. I’ve been looking quite a bit at the comp xe268 and the lunati voodoo equivalent. I think either of those should be in the general range of what I’m looking for. Any input on intake manifold?
