Which cam for a 3000 stall? I hope this is in the right forum but I want to get lt headers & a cam for my car & Im not sure which cam would be the best for my setup. The car will be a daily driver in the warm months. Any suggestions would be appreciated. My current setup is in my sig.
Thanks.
Thanks.
Technically, a 3000 converter is too small for a stock cam. 
That said, a 3000 stall is loose enough to allow an 800 - 850 rpm idle without fighting the car at a stop. The issue is not just duration, but overlap and valve timing. A 222/222 110 +0 would make some serious power and probably have more punch at 3000 rpm than typical off the shelf grinds.
On the street with an A4, you'll rarely see 3000 rpms at WOT (can only do that on a sticky launch) and chances are on a daily driver you'll be traction limited in 1st gear (at least with 3.23s or higher) so power at 3000 rpm probably is not very relevant. Point being is that you can run a fairly big cam since you will almost never be below 4000 rpm at WOT. The biggest consideration is drivability. Since you went with a 3000 stall (fairly mild) you'll probably want a mild cam with nice manners. A 220/220 on a 114 LSA will probably be a nice match. mild lope at 800 rpm or stealth idle at 850. for a little more punch put it a 112 LSA.

whoever said a 3000 stall is too big for a 224 cam, i have to call bullshit.
my car takes off like a raped ape with a 3000 stall and a 224 cam.
while a 3500 stall would be better for that cam, a 3000 is just fine.

Nobody said the 224 was too big for a 3000 stall.
What was said is that technically a 3000 stall is too small for the stock cam. But he then went on and into much greater depth than that.
224 and 3000 stall sounds like a pretty good matchup for a street car that will pull much better than stock with good drivability and nice, mild manners.

Someone had TCI Breakaway 2800-stall with TSP hydraulic roller, 233º/239ºduration at .050, .603/.600-inch lift, 112 LSA. Did he do the right selection?

Assuming the same LSA and intake valve opening point, there is almost no difference in performance between a 222/222 and a 224/224. Overlap changes by 2*so the 224 is a tiny tiny bit harder to tune. I tend to think in in 4* increments when looking at cams because 2* is so small (e.g. 220/220 vs 224/224 vs 228/228). For much more info on cams, you should read/post in the internal engine forum.

A guy I know with a 3500 stall went from a 220-114 to a 224-112 and got no increase in performance but had a major loss of in-town driveability. I would agree with what's been stated above - a 220, or 216/220, or something in that range would be hitting the sweet spot with a 3000 stall.
