Let me get this straight you running a 66 spur and 20 pinion with 1.75to 1 ration tranny. That would make the spur and pinion ratio at 3.3to 1 x 1.75 to 1 ratio = 5.775 ratio. Maxx bling ran a 56 ofna second gear spur. with 10 tooth pinion would put you at a 5.6 to 1. A slightest bit higher but with the weight lost should be good.
