Can you get to 400 without turbo or super-charger

Cant forget your fuel system (pump/injectors), and a tune to go with it.

The price would be quite high, more than likely.

On the other hand, going boosted the safe (and "correct", to many) way would be to swap to a nice forged bottom end, upgrade your fuel system, and get a nice intercooled turbo/supercharger kit. That'd probably last a long time, assuming its all installed correctly. Oh yeah, and beef up that tranny and potentially your rear end if you plan on launching it ever...

This kind of work is common place in the SBC world, and people can, now-a-days, fairly easily put down close to 500 to the wheels in their N/A F-bodies and C5 Vettes for minimal cost. But with these VQ motors, finding aftermarket manufacturers for a lot of the parts would probably be quite difficult, and/or prone to raping your wallet of funds lol.
