I think that would be a pretty sweet set-up. Having a 4.2L with forged internals and a blower on it as well as the oppurtunity to turn up the boost. It would be a fairly cheap set-up too, at least compared to some of the other idea's floating around. The trq that the supercoupe engine makes is very nice. Might be something for the single-port guys to look into rather than doing the 4.2L splitport M112, cheaper for them and just as much power, at least starting off.

If you don't beat on it then it could last for a while. IMO at 350rwhp you are on borrowed time until boom.

the 4.2 motor is still a v6. you can do wither a ford 4.2 entire motor swarp, or stroke the stock 3.8 by swapping out the crank from a 4.2.
