How big of a Cam on stock heads?
What is the biggest cam that you...not can but should put in an LS1 with stock heads?
Also, who has a cam for sale?

If you are putting heads on the car later I would recommend something like the Thunder 224 cam or the 227/224 cam. If you aren't you might want to run similiar duration or lower with .550 lift or less. From what I've been told and the small amount of research I've done the flow numbers of the stock LS1 heads fall off significantly past .550 lift. It doesn't hurt to put a bigger cam in though if you plan to pair the heads to support it later. This is not an absolute I guess but a personal opinon on the situation at the least.
I love my Comp XE-R 224/224, .581"/.581", 112 LSA cam! I've heard two TR224 cams, one an A4 w/ a 900 RPM idle and the other an M6 with an 850 RPM idle, and both cars definitely loped harder than mine does at 800 RPM. My car consistently puts down 361 RWHP with an unlocked converter and 380 RWHP with it locked up. I ran the ET in my sig last night with the car short-shifting at 6,000 RPM on the 1-2 shift. FWIW, peak HP occurs right at 6,500 RPM and hardly falls off to 6,900. Knock on wood, the Comp 918 springs are working great, and I haven't had any issues thus far. FWIW, another LS1 A4 with a Yank PT4200 (vs. my 4400) and a B1 cam put down 355 RWHP unlocked through 3.23's today right after I made 361 RWHP unlocked.
