I always thought if I went back to a stick i'd go with one of these in lieu of a GVOD.
Jerico 5 Speed Drag Racing Transmission
or
Jerico 5 Speed Road Racing Transmission
I have a GVOD, LOVE IT. I'd highly recommend one to anyone thinking about it. IT's a game changer.
But...I would not run on e behind a 4 speed. I'd get an OD manual trans first.
If I were doing a manual trans swap you can bet your *** I'd be putting an OD or double OD tranny in whatever I was building and there are plenty that will take the HP level you will be putting out
