It is a pretty easy swap from what I hear. Pretty much bolts right up. I think some of the wiring for some of the sensors may be different, as well as the EGR valve. That would require a little custom work. And if you just run it with your stock computer, it will run MPFI (multi port fuel injection), instead of SFI (sequencial fuel injection). That will bring down the power slightly.
Are you debating doing this swap?
