I'm doing the GV for 3 reasons, 4 over for towing, double OD for when not towing. Already did the calculations for RPM and with the 8.1 with 4.11 it came out perfect.

3rd reason is just to have 9 forward gears total or 8 on the automatic

If I go nv I need to figure out the best flywheel for 12 inch clutch that will work well on the 8.1 (internally balanced) and the pedals. I checked with southbend and they don't have a better input shaft for the 10 spline

it's only for cummins.
