Hi guys and gals! I saw a peek of grass the other day (just before the latest snow storm and we're supposed to be getting another 8+ inches tonight) and I got to thinking about GOING FAST again! Anyway........ I'm going to be "taking the plunge" and installing an aftermarket cam in my A4-equipped SS this spring and would like to hear from a few folks that have actually done this with their AUTOMATIC TRANSMISSION LS1 F-bodies. My greatest desire, even before the performance advatages, is that I experience NO problems with idling, converter lockup, etc. with my stock PCM programming which I have no intention of changing. Thanks!
P.S.- Right now I'm taking a hard look at the LS6 Z06 cam. Its specs are 207/217 .525/.525 116. Do you think with those lift numbers I can stick with the stock valve springs, at least for the time being? Thanks again.

I went to More Performance's web site where they have listed all the Comp Cams custom cam specs listed so you can mix and match and build the cam of your choice. What do you think of this combo?:
216/216 .524/.524 114
This combo when compared to the GM LS6 Z06 cam (207/217 .525/.525 116) MIGHT be a safe bet not to cause any problems. Its 114 LSA compared to the LS6 cam's 116 should also give its idle just a bit of an edge to it without causing me idling problems.
Alternately, if the 216/216 combo is a little too much duration for my stock PCM programming, what about a cam with the following:
212/216 .521/.524 114
This is the same as the regular Comp Cams Part #54-412-11 that a lot of guys have except for the exhaust duration lessened from 218 to 216.
Also, what about splitting the difference between the Comp Cam's 114 LSA and the LS6's 116 and going with a 115 LSA?
So......what do you think? Thanks!
Steve

Give ARE a call. The heads/cam combo w/ a LS6 intake which was installed w/ an A4 dynoed 419 rwhp and 399.2rwtq at a shop in TX. If those numbers are accurate and you were to add a ~3000 stall w/ sticky tires you could have a low 11 or high 10 second street car on your hands. I believe ARE has a website.. not sure. Go to LS1.com and ask. If you are just looking to install a cam then MTI's T1 cam (don't know the specs but it is radical and not emissions legal) will give you some good power and seems to work good w/ the stock heads. A friend of mine who has one on his M6 w/ a dump and bolt-ons just ran a 8.01 at 89mph in the 1/8th on stock gears.
