What should this run..

im just guessing -- 10.60 - 10.70 , i think thats too much gear / too short of tire though -- a 4:10 might keep it in the rpm range of that combo

I will run mostly 1/8th anyways. But I will run 1/4.. The 28x12.50 is on there till there wore out there almost there. A set of 315x60x15 M/T Drag Radials are gonna gonna go on it they are 29.8x12.4x15..

I bought some more parts today.. 8" converter,Drive shaft,Fuel cell, Manual steering box.
