Buying used cam sets

Is the LSA cam a good choice for a 600whp turbo 5.3L motor?
I found this guy that has a used 09 Z07 factory cam set and this new LSA cam set for sale. $150 either set.

I do plan to go up in power once I'm confident that the truck is running good for a few months. It's going to be a daily driver.
Just looking to get the best value for my money.

Setup is:
stock bottom end
stock 862 heads, but with a stud kit installed
stock truck intake
60lbs injectors
single T76 w/.96 ar
stock fuel rails
320lph fuel pump
T5 WC delivering the power from the stage 4 exedy kit

I think those injectors and turbo are too small for your goals.

what would you recommend? I also have a Holset H2 but it has a 23cm twin scroll housing on it, but I need to find something like a 12 or 14cm exhaust housing just to get the 5.3L to spool it.

It has a twin scroll housing on it now and I was thinking of just sealing 1 side shut just so the motor can spool it.

I think someone else might be better at getting you the right parts. My setup was a 5.7l same turbo 80lb injectors with a 4l60e made 476 WHP. With 600 you will want a stronger trans that will use up some more HP. Maybe Allen or Ray might have some ideas.

Thanks for everything GMCwantsLS1. I also have a 4L80, but I'm already using it in an identical setup in my '54 Bel-Air project.
