i have that issue if CHP, part of the reason i bought it was to see what it made.

actually with just the vortec heads and intake it made 305hp@4700 and 395lbft.@3400. test 2 added a zz4 cam and made 317hp@4800 and 399lbft@3400. test 3 added edelbrock runners, throttle body and a hot cam with 1.6 rr for a total of 354hp@4800 and 427lbft@3800. one thing that i found interesting is that the hp is pretty flat from 4500 rpm to 5400 rpm never making less then 349hp.

avg. hp was:

test 1: 353tq/278hp
test 2: 365tq/287hp
test 3: 400tq/317hp
