Could someone explain to me why you can find a 3:90 gear for the 12 bolt car rear but not the truck. I would like a little more than 3:73 but not a 4:11 for the rear of my 79 C10 but not able to find what i'm looking for. Can my chevy community help me out here.
The other option is to do the 4:11 with and overdrive tranny. 700R4 or 200R4 which one to run?
Help me out friends!!!!!!!!!!
One more thing that maybe helpful i'm getting 450 to 475 @ the flywheel
