Re: Opinions on what 6.0L LQ9 into LSx UPGRADES to do??
I don't want to do anything to the tranny...that's why I bought a 4L80E in the first place (I have a spare 4L60E and a 700R sitting in my garage that I didn't use for this motor).
This is the cam I'm looking at in detail right now as per Shon's post: www.compcams.com/Company/CC/cam-specs/Details.aspx?csid=1097&sb=0[/url] 54-451-11 but there is also the other one 54-452-11 which is a bit lighter I think??

Re: Opinions on what 6.0L LQ9 into LSx UPGRADES to do??
I think that is a better cam selection. The heads you have now are actually pretty decent heads for a stock application. What you can look at are flow numbers of these heads and find out where they peak and where the most gain is at different lifts. These heads still have a high percentage of flow increase between .500 and .600 lift compared to anything else stock. This means you want to maximize the this increase in flow by helping it out with enough cam lift. The GM hot cam was desigend around the flow of the original LS1 heads which were not designed as well as any of the 6.0 heads. That is a good comfortable lift and duration for a drivable, but still "pick-up-and-go" application. I hope this helps
