Anyone that is running a Comp XR276HR-10 have a sound clip they wouldn't mind sharing? I tried looking for one to no avail. I'm starting to put my car back together with this cam and I am anxious to know what to expect.
Thanks!
Jeff

Here is my Comp 276 hyd roller cam, 0.503/0.510", 224/230 @0.05, 112 LSA, (i didn't like the 110 for EFI). Mine is the XM276HR ("marine") but the specs are exactly the same as the passenger car 276HR cam, but on a 112 LSA.
This is a 327 with retrofit roller setup, Holley Stealth Ram, 24 lb injectors, World Sportsman II heads, long tubes, 2.25" dual exhaust w/ Dynomax Ultraflo's, full length exhaust system
It might sound a little different once I get it back together, I advanced the cam 4 crank degrees and swapped the 1.6 ratio rockers for 1.52. I also changed the ignition timing curve.
Drive away. Just started tuning it in this video. It stalled, that's why the video starts with me starting it, and the puff of black smoke coming out. Haha. http://www.youtube.com/watch?v=QMfJeSDq2qc
It definitely has an aggressive choppy idle. I'm happy with mine. I took it to 6000 RPM, and it pulled strong all the way.

I just put in a XR276HR-10 in this summer. I used 1.6 Rockers, so it's .535/.544.

Have you had your setup dynoed at all? or ever had it to the track?

Not with the new setup. I ran this setup all last summer with 2.77's and a stock stall. I can't wait for the 3.73's and 3K stall this summer. It will see the track this summer for sure.
