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

blownhemi said
well 7.70 on the 1/8th equals 11.99 on the quarter so you're probably looking at around 450hp in your average A-body

Very close. 450 h.p. @ 3400 lbs should put you right in the ball park if you don't spin and the car will 60 foot in the 1.8 neighborhood.
