I've got a 400 bb dart and a 360 cuda. The dart shreds the tires cause of the small wheel wells. Gotta think of the full picture before you decide. Best of luck.
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.
