Best cam for my setup?
I used to have an X1 cam in my old car.....and I thought it was very streetable...and didnt have really any problems....drove almost exactly like stock.... some days had to hunt for Idle for about 5 seconds...but other than that it was great....
Now I'm going to go with something in the 224/224 .581/.581 112lsa range..for better low torque and for being not as hard on springs...

I'd do the torque converter before the heads & cam.

Best cam for my setup. I have a 2002 Z28 A4. Will get AFR heads, LT headers and ORY, catback, lid, stall (3000), car has 2.73's. I want good power and decent street manners. Help me pick out a cam for my setup. AFR had recommended a comp cam custom grind (224/228 114) that they have for sale. Car will probably never see the track.
What cam do YOU recommend for this setup?

224/224 114 or 224/228 114 help!!!!! I've got a 02 Z28 A4 with LT headers and ORY, catback, lid, and will be getting AFR heads. What cam should I use and what would be the difference between the 224/224 114 and a 224/228 114 setup? I want good low RPM power and a decent idle.
Thanks!
Thanks!
The AFR recommended cam has all the proper valve events for superior power:
224/228 114LSA +2
IVO 0 BTDC
IVC 44 ABDC
EVO 50 BBDC
EVC -2 ATDC
Overlap -2
If you wanted to a little bigger, try the FMS F13 230/232 with a 112 +2
IVO 5 BTDC
IVC 45 ABDC
EVO 50 BBDC
EVC 2 ATDC
Overlap 7
Notice the intake valve closing point is nearly the same (44 for AFR cam, 45 for the FMS) and the exhaust valve opening points are the same. Solid valve events for AFR heads with long tubes and offroad y.
These cams will make you incredible power, but I'm afraid that 3000 stall and 2.73 gears are a little small for ideal performance with either cam. First thing I'd change would be the stall. You want to run 3500 stall or greater IMO. You don't have to chuck the 2.73 gears if you get the right stall converter.

The 224/228 114 +2 is what AFR recommends. With a proper tune, this cam is very mild and has good bottom end power. In fact, it has power everywhere.

An extra four degrees on the exhaust @0.050" isn't going to yeild much more
power.
It will help scavenge the chamber at mid to high RPM.
Not seeing the valve timing really doesn't tell us much about either cam.
Assuming the IVC, and IVO were the same on both cams, the dynamic compression would
not change at all and therefore you would rely mostly on exhaust tuning to
make any difference with the extended exhaust valve duration.
Do you have links to both cam cards?

I'd agree with Patrick on the cam specs.
Since AFR has done extensive testing with a package, those cams are likely
to perform more effectively than most other cams.
Knowing that your car isn't going to see much track use, I wouldn't stray far
from the proven path.
If you happen to want something a touch more wild, look for a cam with an
IVC of closer to 50 degrees and a slightly later closing exhaust valve.
With the high compression of you engine, shifting the power up slightly (~ 300-
500 RPM), isn't such a bad thing. You might like the extra kick in the ***
at higher RPM when the suggested valve events come into effect.
