How much does it really cost to build a 600 HP 5.0 compared to 900 HP(Forced Induct)

[Coupe50h]

put it this way, that much boost is brutal to a head gasket, yea the forged parts may hold, but you would be looking at a low compression motor to run serious amounts of boost on a "600" hp engine.

600 rwhp is not to common on the street here, there is a few around here, but they only come out so often, because they are usually broke, one of them is an ls1 t/a with a vortech, and a lil juice, he puts close to 600 to the wheels with both power adders.

And you say 500 hp n/a "5.0"? are you talking a hyd cammed, streetable compression engine? no way, not n/a.....

a 408 stroker, with some hefty work can get you that, you need cubic inches, or power adders to achieve anywhere near 500 n/a.
