A Quick What If Question...........

I have a 2003 GT, if i were to put a 4.6L 4V in her what would i need to swap out? I have the 3650 tranny, will this tranny bolt-up to the 4V?

The tranny will work but I think the cobras and Mach1's had a different bell housing for a slightly larger clutch.

Yeah this a debate i have been thinking about doing for a while now. I've been thinking about trading my car for a Mach 1, but then i wondered how much would it cost and how hard would it be to just install a 4V and call it a day. I'm thinking i could save money doing an install, trade-in values suck where i live!!!
