How much HP / Torque with this combo?

I'm picking up my 400 next week and am curious what kind of power you pros think this combo might make.

400 stock bore 6x-4 heads CompCam 270H .470/.470 224* @ .050" LSA 110* Edelbrock intake w/ q-jet from `77 Lemans 3.08 rear end 4 speed ST-10 I'll probably start with the stock exhaust manifolds and eventually move to headers.

Thanks

If you get the valve size, head flow, gas flow, compression ratio and manifold type I can do a dyno on the comp for ya. That stuff is a bit before my time :P

Ok..the valve's are 2.11/1.66" intake/exhaust. Head flow is 210/180 intake/exhaust Gas flow through the q-jet is 800 cfm. CR is 8.5:1

Thanks

Cool ...thanks for checking into it. It'll be a lot faster than the 350 that's coming out of it. I'll definitely have to go with headers too.
