If the porting you had done to the Typhoon was done by a professional, then it should carry that combo. Actual power depends on so many things that estimates are just guesses...........but you should be in the 350-400HP range if everything is well matched.
 
over 400RWHP? - more cam and more intake. i.e. Victor intake and a cam with ~290 degrees duration. A custom cam would be a good buy to help you get your goal the first time. Cam specs don't tell you everything about the lobes>

:stupid:, and a little opening on the heads.
 
I have a graph of an easy proven 400+ rwhp 347 combo.

Milled afr 185's, anderson N91 cam (with valve springs) holley manifold, 75mm tb (minimum) 1 3/4" longtubes and a 3" exhaust. That made 416hp. The guy then put on a ported victor manifold, had the heads worked a bit with a 2.055" intake valve and maybe a 90mm tb and it did 455rwhp.

You'll need at least a 4.10 gear to run good at the track. 4.30's preferred.
