we did one pertty close to what your are building a couple of yrs a go,we had some pretty intense port work done .the boost controller set at 12 psi (be careful with more boost than this without really good rod prep shot peen and such and forged pistons)the cam was a custom grind from a local cam builder(used a 327 chevy cam profile for their fi motor) it made 320hp at the rear wheels but after a boost controller failure on track it kinda flew apart(28psi at throttle lift)it was quit spectactular i have pics of all the broken parts ; )
