Your drag advice needed

Thanks again.
72, im glad you brought the torsion bars up. Im running a turbocharged 4 banger up front, plus some tubular, custom, lightweight suspension and steering pieces. My guess, there will be about 180-200 lbs off the nose when you add up the half motor, half aluminum radiator (and water), custom tubular K and arms, aluminum steering column, Wilwoods, and removed unnecessary sheetmetal. Im afraid even if i crank the front end down, the torsion bars will still have too much tension to allow the front end to settle. Ive talked to some companies about custom ones (im thinking 076) with no luck. Ive talked to guys who have machined some down, and they said it was the biggest nightmare ever, and wouldn't do it again. Lol steel was just too strong, it took forever. I have some 88/89's, and was gonna start with those.

As far as the 29.5x10.5, it sounds like those may not even work for mock up, huh?
