High 7's in the 1/8..how much weight and power??

what i've posted above is for a normal full weight street combo with 3.5 gears. Less weight and more gears will make it quicker, especially over the eighth

2200 is the target weight. Partial tube chassis but still using leaf spring rear. Aluminum floor/trunk floor/firewall.Lexan..etc.. 4.62 gears. '66 Barracuda.
