hooking with 26" slick
i ran 26x8" Hoosier QTP, of course not a radial but less wide than you´d like to use...best 60ft. is 1.60, best ET 11.61....my car is a 1968 Valiant 2dr, medium performance iron headed 408 SB, 3.73 Gears. I think the new tires can do the job for you. I switch to radials too for next season, 255/60-15 ET Street R.....but will change the gears to 4.10 also. Hope for some improvement!
