A lot of opinions here. But I believe AndyF has your best advice. The 470 is a great combination. I'll offer a piece of my own opinion. The cheapest and the easiest on parts is weight. You should be able to dump 400 lbs off your car without cutting it up . You do the math. Easy low 10's
I would go along with the fact that the 470 Is a great combo but at 3600lbs/117mph = around 460fwhp, reduce that to 3200lbs and your@11.12@120.........you'll need another 180hp to go 10.0's@3200lbs, or come down to 2400lbs with current hp to go 10.0's but you won't have much of a challenger left.
