Car weighs 3150 with me in it, has a 430 Dana rear, 3 speed 727, 31x15 big tire...i know there is more in it. Max torque 653 @ 5500-rpm and max hp 766 @ 6600rpm

How high to you guys rev your big blocks?


It really depends on what head is on your engine. However, if you made 766 @ 6600, id bet shifting at 6800-7000 and going thru the stripe at 7000 would work well. You may want to re think your gearing. 3.70? might work better.
Any case if you made your most power at 6600, going much past it is not going to help, even if the engine has light weight components that can rpm higher.(steel or alum rod)

iagree
