Hey, I hear you. I'm not going to change anything. I have a special lifting bracket that lets me lift the engine back into the car without removing the TB's or the linkage, so I'm not going to!
Re: ZF - that's one of my biggest concerns. I have an M1 ZF, which Lloyd Butfoy says is a bit stronger than a regular -2 ZF, but like -2 ZF's, it doesn't like to be shocked. No side stepping the clutch! I also have a smaller clutch assy. than most Panteras. I have a 157 tooth aluminum flywheel and 10.5" McLeod diaphragm pressure plate with an aluminum friction ring. It revs like crazy but gets off the line fine. I use a good old fashioned organic disc with full marcel and a sprung hub. Engagement is beautiful but I know I'll "cook" it if I get too crazy!
