Cam Selection Help
Looking to add a Cam to my 2007 z51 6 speed. Plans for mods are:
Longtube headers/x-pipe and Bullet exhaust
fast 102 Intake
CAI
Looking to get the Texas speed performance kit but not sure what specs I should be looking at. Any venders please feel free to chime in with their recommendations for a Cam package they sell. Looking to make good power with a decent lopey sound but still want the car to be very street-able. Let me know what you guys think! Thanks

This is a great choice from a great place to buy your cam and additional needed parts.

Oh man your in for it! Just kidding, cam selection can be daunting. I just went throw this myself and after months of research I purchased a "Spinmonster" cam which is a Comp Cam. Research Spinmonster cam, Pat G cam, GX1 (LG cam), Lingenfilter and BTR they all make good cams.

Hey Vette_24, I have not installed the cam yet still waiting on a few parts. Mods are Texas Speed SS 1 7/8 headers with Z06 exhaust, Haltech intake, ported LS2 manifold and throttle body but switching to a FAST 102.

This is really the most important question. You need to very precisely determine your threshold of driveability compromise, as well as how often you are ok with servicing valvetrain components (primarily valvesprings). The tuning capabilities nowdays are excellent, so driveability compromises are lessened... but being honest about your driving habits is important.

With a manual trans you can get away with a much larger cam than with an automatic-- and drivability won't suffer badly
A FAST 102 set-up is most beneficial for a car that has
Larger than stock cubic inches
Consistently run above 6500 RPM's
Huge cam---
If your planned use does not include some of these parameters then most likely you'll never see the benefits of a 102 setup
As far as the cam goes
depends on whether or not you have to pass smog or want to
Let's assume you don't need to--- On a manual trans I would go for something in the mid 230's range to retain some drivability
Lift doesn't really matter--however above .600 would require to change valve springs every couple years
If you want a lopier idle --The LOWER the LSA the more lope--Stock is about a 117-119
A real lopey idle requires an LSA like a 112
A middle lope idle is achieved with a 114 LSA
anything above a 114 will have a stock sounding idle
However anything lower than a 114 and a duration @.050 above about .224 won't pass smog

So in California now there is no more tailpipe test, at least for the newer model cars. Just a OB11 diagnostic check to see if all emission utilities are a go.
So I would think any size cam would pass, or am I mising something?
Does a cam change to large set off a fail code, without the tail pipe test.

The LS2 Intake Manifold is known choke point.I have an LS2 and very mild GT11 Cam + fast 102. I picked up 25lbs TQ (over a ported stock intake) @ 2200 RPM. Low end Tq gain was outstanding with the Fast 102. Peak Tq was up over 40lbs.
