Rear Gear Question

[gsa612]

I run the same 402/315 but in a Camaro, it all depends on the cam, lobe sep.etc. I run a 4.56 with a tight cam,2.75 low, 4800 flash.I think you would lose 60' and ET with a heavy car like yours by changing the SLR.You can get away with a little more rpm on that motor because of more exhaust lift (.430). If you run the big hoosiers 94" as opposed to the 92.5" it will give you around 200 rpm. gsa612
