I am going to be running 9:5 to 1 compression on a Forged 346 LS6 motor (which i am going to start having built in the near future) for my 02 Z06, powered by my ECS D1SC Procharger kit, which is a street car and will see between 8 to 14 lbs of boost at any given time on the street and occassional track day (both roadracing and a little drag racing). Also, important to note that i am going to be running my new forged set-up with my 100% stock LS6 head (except for valve train upgrades for the new cam).

I want a fairly agressive cam without going to big, which will make great power off the boost and on the boost of course, and am thinking of something like a 226/232 cam on a 114lsa, with a .588 lift. or 224/230, 114, .588 lift.

What cam do you EXPERTS here recommend for me for the my custom CAM specs for the use of my car as described here.

I certainly don't mind running a little bit more of an aggressive cam similar to the specs set forth above, but don't want to overdo it as my 02 Z06 is primarily a street car, but would like to have a nice midrange HP increase when i am not seeing boost and running the car between 2000 to 3000 rpm, etc., but of course most importantly, I need the cam to perform like a champ when seeing anywhere between 8 to 14 lbs of boost at any give time!

THANKS and yes, I also posted this in the F/I section, but am not getting as much feedback as I would like!

IMO, you want the exhaust lobe to mimick the valve events of what you would need if making 600-650 rwhp on motor, but you'll need a shorter intake lobe and narrower LSA to keep the overlap under control. High lift on the intake lobe would make the curtain area larger, allowing more pressurized air to enter.

Something like a Thunder Racing CheaTR (215/230 .600/.578 117LSA) would be great, but I would go a little bigger:

220/236 .632/602 114LSA +0

Running a lot of intake duration is not necessary, but plenty of exhaust duration is. Power off boost will be good because of the shorter intake valve timing.
