LQ4 6.0 Torquer V3 Sierra start and idle roll out

Start and idle/roll-out of my LQ4 sierra. Texas Speed Torquer V3 cam. Truck put down 411whp and 530whp with a 125 shot.

This truck just had bolt ons and a pretty hefty cam. Stock heads, stock bottom end. With a nice set of heads it would have woken up A LOT.
Mine had longtubes, TBSS intake, and 100mm throttle body. It was tuned for nitrous so it would have made a little bit more if it was tuned for motor only.
I think you could hit your goal pretty easily with a nice set of heads and a healthy cam

What all was done to the truck to put down that much? I'm building me a 6.0L right now. Putting a Gen IV 6.0L in my 04 Silverado. I'm wanting around the 430 to 500 mark no power adders.

I'm doing a 6.0 lq4 swap in my chevelle and have been considering this cam. Did you have to butterfly cut the pistons for ptv clearance?
