is it just me but if you are looking at 425rwhp, shouldn't the stock block and internals be fine for that? To me for another 25rwhp, why spend all that money? Now if you are looking for around 500rwhp I would definately do it. The stock block should hold a low 400 with a good tune.

+1 a.k.a hotmustang331
+1 for hotmustang331, he had his twin turbo gt to 500rwhp on stock bock. Just need luck and good tune on your side.
425rwhp shouldn't be any problem with good tune.
HP ratings in turbo applications vs supercharged are quite different. If you dyno a turbo engine vs a supercharged engine, even though they can make the exact same power at the flywheel, the supercharged engine is making 50hp more just to power the supercharger. Think in terms of cylinder pressures. A 425hp supercharged engine has the cylinder pressures of a 475hp engine after you accound for the blower drag. The turbo engine making 425 hp at the cylinder pressures of a 425hp engine still.
