600hp turbo ls1 cam?
An aftermarket cam will move more airflow at the same amount of boost as a stock cam. Meaning more power on the same amount of boost until the turbo can no longer efficiently supply the airflow the engine is demanding.
An aftermarket cam can help with spool time and it can increase the operating range of the engine, but mating the camshaft to the combination and more specifically the turbo is very important.
Is this a 5.7 LS1 engine?

I was asking how much RPMs it drops on the shift. But if you are changing the turbo don't worry about that question for now.
Sounds like you are trying to get around 9.90s in the 1/4 at your weight I'm thinking that's 7xx crank HP. I think 14-15 psi would get it there.
I ran a 5.7 with pistons and rods with a GT47-88 20 years ago and went 9.40@147. I went 10.0@139 on pump gas.
I hit my SBE 5.3 gen 3 LM7 with 18 psi to go 5.6@127, Wallace says 920hp. And on May 8/9 I will run 5.3-5.4 or break it lol.
