Okay, you purists are going to have trouble with this one...sorry for any offense I cause, but let me begin by saying I am a Chevrolet lover and I love AMERICAN muscle cars....I am 19 yrs old and new to this forum and I am planning to swap a chevy small block 355-383 into my 1995 Nissan 240sx (a little japanese car known for drifting)...

I just wanted to consult such experts as yall to help me out, what is a good combo to go with to make a nice 400hp to the wheels, but mainly big torque. I am stuck on the 383 for the torque and lope. Not going to need high rpm, but will definitely be driven hard at drift events yet still will be a daily driver.
I've thought about the DART shp block ($1500) with a forged bottom end, simply because I want the strength of forged internals....but is cast crank, powdered metal connecting rods, and hypereutectic pistions suitable for such a motor?

Please give me some feedback. What do yall recommend for 400-450 hp/ 400-450 ft/lbs torque? THank you in advance, especially to TECHInspector, lol.
