7 1/4 suregrip?

Yes the sure grip would help A little. The valiant we just sold, 318 car came with the 7 1/4 and held up for 90,000 miles before breaking. We also know of 13. sec cars with the 7 1/4. dont know how long they last horsing around. We did up grade but not cause it broke. We went with the 8 3/4 for the quick change center unit. 8 1/4 WOULD BE FINE FOR SOME BURNOUTS, I'M SURE:-D
