Default Ls1 build, hp gain?

Through various trades and deals, I've got a stock ls1 short block assembly, hand ported 806 heads, 5308 Z06 cam, and long tube headers i'm thinking about putting together. With a good tune, what kind and hp/torque gains would you expect this combo to make over a stock setup.?

Thanks. I'm a newb to these motors. I was wondering also if aftermarket cams would provide significant power increase over the Z06 cam and still have good drivability. Really dont want to spend the money unless there was a big increase over the Z06. Car is a 98 Z28, T56.. Just want a solid street car with limited strip action

Ooooh Yeah!...lots of bigger cams than that one that are DD (with a tune). Also pick up a LS6 intake.

I think with that you should be in the 370 range at least on most dynos. If the 806 heads are ported well then you can add to that. A stock z06 with that cam and 243s makes 360ish even though your heads arent as good they shouldnt be that far off ported. People underestimate the ls6 cam.

However with that said, you can get a lot more performance and keep driveability. A 226/230 on a 112lsa would drive real nice and make good power, or you could step up to something like a 226/234 or 230/234 depending on how much you want to give up for power
