^^ that helps abit. But I'm still trying to figure things out.
For quicker revving along with more power (obviously), what setup and brand should I be looking at?
Chiefy, you need to find a pro and talk to them. Ultimately, it is want you want the car to do. If you want to just run thru all ranges of the RPMs, then you might want a cam that has more mid range torque. Ultimately, the cams that make the most power up top are the ones that are gonna get you down the track faster because if you are shifting for optimum performance, your RPMs will be above 4k the whole time.. I think that is the cam you are wanting. In my ZO6, the stock cam was very good at this. That is how they got 405hp out of 346CID. It is the first(and only) car I had ever driven that went thru the first three gears like a dirt bike....just braaaaaap....braaaaaaap....braaaaaaaaaaap. And there you were at 100mph in about 9 seconds. It also had a "powerband effect" like a dirtbike. Once you went above 4000rpms it was on!!! This car has a very similar drivetrain to that car....same horsepower with basically the same gears and tranny. I just think the cam on the LS2 is more of a mid range cam versus a higher RPM type of a power curve.....we have the same power with more displacement. There is some low hanging fruit(displacement) that a different cam may be able to take advantage of.
Another question is how each of the numbers will affect the driveability of the car. The bigger the lift and duration, the more lope you are gonna have. If it gets too big then your car may have trouble idling....do you want your sweet machine dying at a stop light? I know I don't. To correct this they may have to raise yur idle to close to 1000RPMs....not really that big of a deal unless your car is loud as hell to begin with. Lobe Seperation Angle(LSA) is a way to offset this. The LOWER this number, the more lope you will have....and nominally more power. What you will find is guys will go aggressive on the lift and duration and try to tame the beast with the LSA. A 111LSA is pretty damn lumpy whereas 114 or 115 is more tame. So alot of people will go aggressive on lift and duration and have a more tame LSA at the expense of 10 or so HP.
Still another question is how emmisiions compliant do you need to be? Bigger cams will not pass emissions due to the fact that there may be some overlap in intake and exhaust which might allow unburned fuel thru the exhaust....not good for emmisions.
Again, know exactly what you are wanting your car to do and then portray that to your trusted local tuner(maybe even non-local). Most tuners are more than happy to explain the basics to you.
Most of my experience has been with the LS1 and LS6 engines so my numbers above might be off a bit. I am still getting familiar with what is common to the LS2.
I might sound like I know what I am talking about but I really don't . This is just scratching the surface. Talk to your local pro. Good luck.
