Stock L76 longblock...TSP or TR TruTorq?
Stock L76 longblock...TSP or TR TruTorq? Engine is stock L76 so 6.0L with 823 L92 heads. Just had heads resurfaced (~.003-.004") and PRC duals installed.
So TSP has some nice cams...
225/230 .617/.612 111,112, or 113 LSA
229/236 .624/.615 111,112, or 113 LSA
231/239 .641/.615 111,112, or 113 LSA
I had read somewhere that someone tested them and got like 6 hp less from the small vs the large but gained down low. Sounds good to me and easier on springs.
I also noticed that Thunder Racing has some nice claims on their TruTorq Level 5 cam
227/239 .614/.621 115 LSA
They got 481rwhp/434rwtq on a 2010 Camaro SS w/ headers only through the TR6060 (I have the TR6060 as well)
It seems that the TR cam may be the better choice with lower lift (longer spring life) but then again some of you may have some useful info before I drop some $$ on a cam.
Thanks!

The lower lift doesn't determine a spring will live longer. It's often more the spring & lobe designs that determine it. Currently the TSP cam packages are on special with a .675" spring upgrade free! Checkout the camaro5 site & search the TSP camshafts. We engine dyno developed all of our LS3 camshafts side by side with many other grinds when we determined what combination works best with these heads/intakes/engines.
Nobody spends anywhere near the time developing & testing camshafts like TSP. Here's a pic of the engine dyno while cam testing was going on:

Actually the stock LS3 head has terrible valve placement in the heads. that's part of why the PRC 250cc aftermarket casting LS3 heads perform so well next to a ported stock casting with nearly 20cc's smaller runner!
