Depending on the heads you get you could see anywhere from 20-45ish gains.
With a GOOD tune most will tell you up to a 150 hit is safe but a few have gotten away with a little more...

Heads or if you want a significant amount some nitrous. If you have a good tuner I would do both.

I would add some trick flow or afr heads to the mix. 40hp should be gained. n.o.s is great,but more stress if you hit it all the time and the bottle runs out. I don't even spray a full bottle a year.

what cam, like what are the specs? I would say that a good set of heads and a fast intake would be a good idea i assume the cam is pretty large to be making that power in an ls1.
