I have a 306 with 93 cobra heads ported, trickflow stage 2 cam and c4 tranny w/3200 stall and trans brake. Tires are 26x10.5x15. I will be running nos w/ carb plate maybe 150 shot. Question is what would be a good set of gears as far as ratio goes for a 1/8 mile track? Any help would be great. Thanks
