Ok what gears should I get if I am planning for a whipple? Ithinking 4.10s but what brand has had the least problems. Ford, motive, Pro 5.0???Any help would be appreciated.

Wouldn't go with 4.10s and a blower. Traction issues. Motive gears are junk. I'd get the ford racing a code I believe they are. Don't get the ford racing motive outsourced ones, I think m code at end of #.
