I have seen the stickies on v6-v8 and modding 3.4 and 3.8, but does anyone know anything about going from 3.4 to a 3.8? I assume the computer is different but I could get a 3.8 ECM. Is it a straight out swap or will it be one of those things just buy a new car?

 

I would just buy a new car. There isn't really much you could carry over from the 3.4 to have for the 3.8.

 

it would be just as easy to swap an LT1
