Set it so you cross the traps at 10% higher than the peak HP rpm The only reason to vary from that would be something like a stroker with small heads where it would lay down after peak hp real quick. 8..603 156 mph best, 2905 lbs 549, indy 572-13, alky

Actually that is kind of what I have. Was built for good torque and gas mileage. Goes like hell to about 4800 RPM then just lays down. I'm leaning towards 3.73 ratio.

Still comes down to the same thing... but your HP number is lower
