This combo isnt something new, guys have made over 500HP on the same cam/springs. Here's just one link I bookmarked because he also has the little 4.8L, Ls6 spring and small cam. This is thru an auto at 11psi, same turbo/manifold I run. However, there are other dyno threads and feedback I based my choice from on running this setup. Again, i'll let you guys know if I have any issue's. Worst case, she drops a valve and I'll have a reason to put lq4 in and add a few millimeters to the turbo. Not really that worried about it to be honest.
