I have 295-50-15 Radial T/A's on my 71. 10" rim with 5" backspace. But it ended up rubbing on fender lip a little, so I rolled it up. If I had to do it over again, would try 10.5" bs to tuck in tires slightly.

Regardless of whether you want to corner or accelerate better, you need to remove all the rubber and slop from the suspension. They make poly subframe mounts, which are a little quieter than the aluminum. Neither are that bad on the street. I am replacing all the bushings front and rear with poly in my 70. For handling, I would go with the 17", for drag racing, the taller sidewall on a 15" would help out traction. I chose 17's for mine, 17 x 8 with 4" bs fit fine, you can go to a 9 or 11 inch on back if you do a little tweaking. I decided on the same size front and back, so I could rotate my tires

What do u mean quieter....do they squeak or what do u mean...also what about adjustable end links on a sway bar... plus how easy is it to bend the 17in rims...i have 400hp/th350/3.73 eaton posi..will p295/17 hold the roador should i just go with p295/50/15///also how high can u rev a stock short block/with balanced rods without spinning bearingsan tearing up the bottom end....the cam/heads/manifold/HEI are good through 6500rpm but will 6500 hurt the bottom end....thanks
