Hey Bill I'll make it easy for you,just buy my 360 magnum stocker motor for $3500 and run low 12's at will with your current gear and converter!! Hell..,I ran 4.89 gears on the street for 10 yrs with no problem. I used to DRIVE 3 hrs to Norwalk,Oh. with a similiar set-up. Of course I was young and fearless back then!!
