Lets see, your 20, and want to run boost on a 350hp SBC. In a truck, with no, and I do mean NO weight over the rear tires...

I would say build you a stout 350ci SBC, 10.5:1 or so compression, good streetable cam, good intake, and a well balanced carb breathing out an equally well balanced exhaust. I think you will find that 300-350hp is just fine for a driver, and much easier to manage without getting too far in over your head. It is still enough to get away from you, but much more forgiving than a boosted engine.

If all you want is a extra bit of oomph, I would recommend leaving the compression around 9.5:1, and installing a conservative shot of N2O. You will get the punch you want, with the benefit of not having it unless you mean to.

If you have never owned a boosted car before, I would suggest making friends with some one who does. Or go test drive a boosted car, one of the smaller 2.0 liter cars to give you some appreciation of how it feels. My VW with a boosted 2.0 made just over 200hp, and my friends boosted 2.7L V6 Saab is right around 300. That one will get you a speeding ticket before you get into fourth.

A boosted SBC is no joke. Putting the snails to a 350hp one will surprise the **** out of you, even worse if you don't know how to deal with the boost.

I have seen guys who have built their own engines, driven them daily, and raced them regularly, still end up in the wall. **** can go sideways REAL quick.


If you are dead set on it, I would suggest no lower than 7.5:1 C/R, and NO MORE than 5lbs boost.
