Did you look at the link i posted? Some of them have way more than you will ever do to your car and are making 260 ish. You are not going to get 300+ NA out of the v6.

Yeah even if they're going by crank hp theres no way they have n/a's putting down 390hp.

If you build an engine for serious f/i (like you stated), you have to lower the compression ratio = takes away n/a power. Anyways, hp is kinda meaningless, there are many other factors that make a car quick. HP #s may talk the talk, but 60', 1/8, and 1/4 times walk the walk.

Aka torque. 4.3's are great for the torque they produce.
