Cam Review on C6 (Comp vs Crane)
To give a little history on the car it is a 2007 C6 Z51. The car had a comp 234/238 .598/.605 112+0 installed along with American Racing Headers, X Pipe with CATS and a Vararam. This combo made right at 400hp and ran consistent 119 mph at the track. Overall I was a little disappointed with this setup as I didn't feel I had the low end I wanted and she just didn't do as well as I expected at the track with the trap speed.
Fast Forward to this year. We added a GLM (Green Light Motorsports) ported LS2 intake and TB. This seemed to help the car with a little more top end, but still wasn't what I wanted. We then decided to swap the cam to see if we couldn't gain a little more down low and make some more top end power. We decided to go with a custom JPH cam from Crane. (234/242 .624/.605 112+3.5). I had some reservations at first as all we have used in the past were Comp cams with great success.
The car is night and day different. I have yet to put it on the Dyno but after tuning it, it is obvious from the cylinder pressure and manifold pressure readings the car is making a lot more power. (The SOTP meter tells us the same). From 3k rpms all the way to redline this thing pulls HARD! We did a few 140+ testing runs and were very impressed.
The car has a nice lope with the stock catback. You CAN tell there is a cam in the car, but we were able to smooth it out with some fine tuning of the spark tables. Drive ability of the car is fantastic. The original 234/238 was in my F-Body and you could feel the effects of the cam. The only way you know this is in the car is from the lope and small surging you experience when in the lower RPM range trying to creep along. 3.90+ gears would be recommended and take care of this problem.
All in all I am in love with the current setup. I can't wait to get her to the dyno and track to see exactly how much she picked up.

In my opinion, you are out of head. That is a big cam for everything else being stock.
In other words, if you swapped out the stock heads for ported stock or high flow aftermarket heads, you would get a huge power boost. Also, long tube headers would be a good idea.

I am running American Racing Headers on the car. I am aware that a nice ported set of 243's or AFR's would give me a nice increase, but that isn't my goal at this time.
