Money will soon be no object for this, my motor is approaching 110,000 miles and with all the work Ive out into the rest of the car, the engine and transmission are the last things Ill be replacing. It sounds a little retarded but Ive known people who have Vipers and a complete 2003+ engine and tranny pullout sounds attractive for my 2001 Mustang GT. The things Im aware of are transmission housing height, engine compartment space and transmission length in relation to a new drive shaft (of what model I don't know). I also know that whatever rearend work I did, it would have to stand up to nearly 700hp... Shaving inches off the transmission tunnel or replacing it all together are probably things Id have to deal with if I go this way, Im thinking also front suspension work to compensate for the much heavier engine. If anyone has INPUT rather than INsults, please dip in. Does anyone know of what kind of drive shaft, rear end and suspension upgrades Ill be looking at if I did this? Bear in mind it'll be a complete pullout with all wiring.[/img]
