th350 shifts harder in drive?
im guessing to fix the overlap is it valvebody related or shimming a clutch pack tighter?
If this vehicle is for drag racing/weekend usage with very little street miles install a reverse manual valve body. Most reverse v body's have no low clutch apply, and also freewheel in second (by eliminating the coast band).
This cleans up both the 1-2 and 2-3 shift.
If this is not a option for you, and your purpose of manual shifting is to raise the wot up shifts, then lighten the weights/springs on the governor to get the wot rpm where you want it. (note: this is kinda a bitch to get the rpms you want exact...takes a little time to do.)
