CAM Comparison
I am getting ready to buy a cam and I am considering 2. One is the GM "HOT" cam and the other is the Lingenfelter GT2-3. Both spec using the Z06 valve springs and come with them. May or may not do the rockers and pushrods. Car only has 38K miles on it.
Want to keep a good idle and around town manners.
The GM cam looks like a Z06 cam.
Lift: .525'' Int. / .525'' Exh. w/1.7 Ratio Rocker Arms
Duration: 219° Int / 228° Exh. @ .050'' Lift
112° Lobe Centerline
The Lingenfelter looks a little hotter, but I am not sure of the impact the duration and centerline would have.
Lift: .571'' Int. / .578'' Exh. w/1.7 Ratio Rocker Arms
Duration: 207° Int / 220° Exh. @ .050'' Lift
118.5° Lobe Centerline
Any thoughts would be appreciated.

I would suggest what's sometime referred to as the "Tony Mamo" cam, which is 224-228@ 114, and about .575 lift. Great all around performance gain, and stock drivability, with a small lope. Also will pass CA. emissions. You really need to do springs at the same time. The cams on your list are not worth the expense, IMO.

With install this is about $1k so i would rather pick a better cam. Don't need to push the peak power at the upper RPMs as much as low to mid-range torque.

The latter of the two would be the smoother running as it has less duration yet more lift though neither are going to increase low rpm power. So I'd recommend getting a custom spec cam to meet your goals, more lift and an early IVC will help low end power. Feel free to give me a call if you would like to discuss details, do you have headers?

You really don't have to have anything but the springs, BUT..... it doesn't hurt to get better pushrods, new lifters, new lifter trays, and a better oil pump. A cam installation means you have to pull the steering rack, so if you haven't already replaced the stock balancer, do it now, and pinning it would be cheap insurance. Stock rockers work OK, but have failed with disastrous engine damage, so there's a few ways to prevent that. As you can tell, modding is fun, but a slippery slope from a money spent perspective.

Probably will do everything rockers, pushrods, lifters and trays, and balancer. Oil pump is cheap (compared to the other parts) so I guess I would get that too.So now i'm at $1500...LOL. Cam is coming as a gift install and the other parts are on me.

I will reach out to you for the cam.
