Hemi 4 Speed?

hi, the hemi trans will have 18 spline input shaft, others have 23 splines. the hemi gear set is a coarser cut, versus others. the slick shifted trans lives quite well for racing. they can be driven on street, just have to learn how to double clutch when shifting up or down. as for life on the strip, mine has 2750 passes on it!!! with original pro rings. its in a 3400 # stocker.
