Get an LS3 and throw a cam in it. Or just settle for 400-420ish unless you want to spend money.
I have a 2005 C6 and I tried to get 500+ out of the stock 243 heads and intake but never happened. Ended up building a 408 and has prefect street manners making 570rwhp on motor before spray.

Maybe go this route.....

apparently it's a cts-v lsa engine, and the owner claims that the only thing he did to it was change the pulley on the supercharger, polish the supercharger, and install a spacer.....seems pretty easy for 800hp at the engine, 635hp at the wheels, and 650ftlbs of torque.... I watch all of this guys shows, there are quite a few ls builds on them and they seem to all make uncanny hp... including the 1200hp nova.

308 is right about intake limitations too some brags are BS on gains with their intake. You have to go long runners & bigger ports all cost money, money and more money.
