So I just wanted to get some thoughts from all you mustang buffs. I am sick of fiddling with my current lemon engine that i got when i bought the car, so I am replacing it (already bought the engine) with a 2005 or 2006 4.0L v6 from a newer mustang. It is a new engine. Good idea or bad? I am also getting a new transmission. This is only the beginning of the mods I plan on installing in this bad boy.
