When settling on the final drive ratio what should I shoot for? Peak torque or peak HP through the traps?




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.




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.
