FI LS3 cam help

I'm looking for advice on a cam for my 6.2L L92/T56 conversion into a 3800lbs 1970 GTO.

I will undoubtably go FI route but I'm currently undecided on going TVS/Whipple/Twin Turbo and running approx 10psi at a goal of >600rwhp/tq.

I have the stock L92 cam setup in the pullout. I also have the stock LS6 cam/valvetrain from my sold CTSV below. I was also considering just getting a LS3 or other stock cam.

Also do you have a spring recommendation for this motor/10psi? I have the yellow LS6's as mentioned above.

Thanks.

The LS9 (ZR1) cam comes to mind. I've used the PRC springs before with good results.

ive used PRC duals, 650 lift and the ZR1 cam, and also pac1218s with the ZR1 cam and they work excellent

21lbs of boost so far on the drop in pac 1218s. they are awesome

Sounds similiar to the SNL blower cam I had but I don't know much about cam specs---which is why I was primarily looking at stock cams.

My SNL cam was a 22x/23x .6xx/.6xx 113lsa

It made great power and was tuned very well but I'm thinking maybe something just a little smaller for idle and city driving?
