I would like to know if I left any on the table. I recently purchased a spool and 4.86 gears for my 72 Duster: 3060lbs(w/me), 340 .030 over,ported J heads,Racer Brown STH-42cam,1 3/4 headers, 2.74 low geared 904,29.75 tall tires, 4800 converter....crossed line @6200 w/4.56 gears. I was thinking if I went w/5.13 I would spin too far out of the torque curve.
