LS6 intake tb max power supported?

Does anyone know what the most rear wheel horsepower/torque the LS6 Intake and Throttle body can support?

I'm guessing around 500 since the C5Z pushed out 405 to the crank. I could be wrong.

500 seems to be the consensus, in my experience.

500 RWHP would be just above where I am targeting, so I guess heads, cam, minor overhaul should be in order!

What intake manifold do you have (or are planning on)?

I run a p&p throttle body with an LS6 intake feeding machined heads and a mild cam pumping air through stock exhaust manifolds and am making 360ish at the wheels (elevation is about 1100 feet).

I don't know, but I assume that once I get some headers, I might hit that 400whp mark.

You planning on a big cam?
