Gen IV LS3 build elements

[71RS/SS396]

I would use the LS3 525 cam and springs, GM did tons of testing on that combo, it makes good power and is easy on the valvetrain. The question is... how good does the car handle that it's going in? The higher the grip level is the more time you need to spend on helping it keep oil where it belongs. A oilpan with good baffling (I'm a fan of the Autokraft pan), accusump, oil cooler, and good venting on the valve covers and valley through a catch can.
