How much HP?

if you don't have this already consider them. lite weight rims, lite weight front tires, bias slicks 29.5x10.5x15, 4 12 way adjustable shocks, the biggest u-joints front and back, at the least superstock springs(002&003) or an adjustable ladder bar set-up with either a floater, slider with stock springs or coil-overs, tie the frames together, 12 point cage, driveshaft loop, trans blanket or shield, mini-tub, 4.10 gears, 4500-5500 converter and manual shift 727. the biggest slick I've been able to get in my mini tubed demon is a 31x10.5x15 and this is with a lot of work to the top outside and front and rear of the wheel houses. if you notch the frame half way in and box it back you should be able to get a 3" wider slick to fit. if you back half and tub you can get any size slick to fit. all this and you should be able to get all your hp to the ground with no problem and pull some pretty dang gum fast numbers.
