Big Block Conversion, do it again?

If your dart shreds the tires something is wrong with your setup. A 10.50 tire fits in the stock well on a 67+ dart. Have you ever seen the times people run on 10.50 tires?

My car is a small tire car and goes 11.70's on tubeless street tires with street pressure.

A-bodies have room for plenty of tire. My '67 cuda with mild 440 dead hooked on the street with a 9 x 28 tire to high 11s, and that was 20+ years ago. With today's tires and suspension there's no problem at all.
