Z06 Cam question, need input I have a 2002 camaro SS w/ 5k miles on it. I'm planing to drop in a Z06 cam along w/ jet hot lt's/cats, ported LS6 oil pump, air lid, ported MAF, Ported TB and posibly a crank pulley. I've seen threads of people using stock lifters w Z06 springs. What I need help w/ is: Should I switch the stock springs to 918 beehives? Would it be better(hp wise) to get .050 longer pushrods?
Eventually the car will become a daily driver and want reliability to go with it, hence the mild cam. I'm looking for a mid 12 sec ET, and plan to eventually change the rear gears (3.73 or 4.10) followed by Patriot LS6 or LQ9 heads and then an STS turbo. To start I'm looking for 400 rwhp and then move up to 500 w/turbo.

My advice is to choose a different cam. I currently have this cam and am getting ready to swap in something a little bigger. My car is also my DD. There are a lot of very streetable cams that make real power.

Yes, you need to change your stock valve springs. You can use the 918's, or just the stock LS6 springs. If you think you might change cams again down the road, put a good set of springs in to start. You wont gain anything with the longer pushrod except more lifter preload.
Lately with the bigger cam craze going on I would say get a bigger cam. The LS6 cam would be good for forced induction, but if you plan to stay N/A I would say you go bigger. You wont regret it in the long run.
You have a 02 oil pump with 5K miles on it. No need to replace it. Don't port the MAF. I would run stock length 7.400 push rods before I would run 7.450s. The correct length P/R for an LS6 cam with LS1 length valves is 7.427. No one makes an off the shelf P/R in that length. You could custom order some, but the stock LS1 P/Rs will work fine. That's what GM uses in the LS6. LS6 valve springs are now sold as a kit under part # 12499224 for about 1/2 of what they were sold for individually.

CompCams makes a 7.425 Push-Rod. You can purchase them from ThunderRacing... $132 for a complete set I think....

I'd put a slightly bigger cam in it for now. LS6 does nice, but you can make more power and have same driveability & ease of tuning with a slightly larger cam such as a 212/218 114 or even a 220/224 115. Otherwise buy a cam designed for the STS turbo if you truly think that an STS is in your future.

Thanks guys, I'm trying to get the Z06 cam for under $200 bucks. I saw that Thunder Racing(I'm in La.) mentioned needing to change P/R, but I'll stick w/ stock then and just pick up the 918's. Now that STS is offering financing, I should have the Turbo by May. So F.I. is in the very near future. Any recommendations for a better cam for the Turbo? Or should I check the FI forums?

I have the stealth II cam. Setting on my work bench, it's going in the end of Feb. I've seen some very impressive #'s with an almost stock idle. You should check it out. BTW It's 224/220 581 lift.

Cool guys! Scrub the ported LS6 oil pump, and ported MAF and that's another $200 towards a bigger cam if the Z06 falls through. Otherwise I'll post some numbers the first week of april with the fore mentioned setup. I'm looking for about 350/350 to rear wheels to start for a small price just to get a little more out of the Turbo.
