Big Block or Small Block?

I am planning on building a high performance street engine. Should I go with a naturally aspirated big block with a decent cam, or should I go with a supercharged small block? I have looked into Procharger centrifgul supercharges and thay make some pretty impressive numbers.
Thanks.

SMALL BLOCK MORE SPEED!
AND LIGHTER TOO

What Size Engine?
Dual Carb Or Injection?
Supercharger W/o Blower?

you can build a screaming small block strocker motor!

In this instance, I would say go with the supercharged smallblock, but that built is going to get VERY expensive. If you have somewhat of a budget and want alot of streetable power, i'd go with a bigblock.
