1971 Scamp performance

I got a 380hp crate 9:1 cr, similar cam, single plane, 2.xx something rear gears and 2800 rpm stall I can burn my tires no problem, don't take that much hp to do so. At 2800 rpm the hp your making is about 53% of torque, minimum probably around 340 lbs-ft to 400 lbs-ft = 180 to 210 ish hp more than enough to burn some rubber.

My guess somewhere in your tune.
