If money is no object, swap in a 2010 zr1 powertrain (good luck finding one). If money is a some what object, swap in a LSx powertrain from a camaro, transam, gto, ssr, etc. Then put a blower on top of that. Plenty of power with still having great drive-ability, can even run a/c.

Got 15-20G to blow go ahead youll need at least that much to upgrade everything else to handle the power. Why even think of a smaller motor if youre going that route?

Rearend 5k minimum
Turbo 400, a real one could be well over 1000+ converter
Motor-depends + fabbing, cooling system brackets etc etc etc.
Plan on spending 20k if you get out for less youre lucky...if you want to build it right. Plan on a cage to as the car will need some serious stiffening up. See if you can find one thats already done.

Jerkyboy has an incredible 434 sbc C4 (13k) not sure if he sold it or not. No blower but it will keep up with most anythign out there and had a great job done on it.
