The lobes used on that cam are a newer generation and are more stable. Spring life will depend on spring choice and proper setup. I have had a set of Comp 921's on three different engines with 3 different camshafts all with .630+ lift. I test them every 10,000 miles or so. They are still going good with my current setup in my CTS-V (.640" lift) for over 10K miles... I would have to say they have over 35K miles on them now.

Oops! Sorry. We actually have a version of the CheaTR specifically for FI. It is a very similar grind, almost indestinguishable. I have a customer in FL with an '04 Vette and an A&A kit making mid 500's on a stock block @7PSI through an auto with a CheaTR.
Thanks,
Shane

what springs are needed for the fi cheatr cam? i am considering running an ls6 cam with a 5.3 and more than likely a t70 masterpower turbo at about 15-16psi. wondering if it would make more power with your cam? want stock like idle though.

The minimum spring in that particular application would be a Patriot Extreme but if you can afford a little extra, I'd go with the Comp 26925 or even 926's. The added pressure on the seat might be a good idea at that boost level.

It really just depends on how many CFM you are willing to push through the motor. This cam is just a "big" LS6 cam. You will make more power on less boost all else being equal. You will have stock idle quality with good deal larger intake and exhaust lobes. In an NA application, this cam is usually good for 35-40RWHP over an LS6 cam.

They'll work in the stock spring pockets. Ti retainers are available but the tool steel retainers will last indefintely and are much cheaper. I believe they are 3 grams apiece heavier than the Ti version.

I should of researched it, I didn't know the CheaTR package came with AFR 205 heads, no wonder it is more expensive. I would def get the CheaTR over the other package in that case. Those 205s do wonders with these stock short-blocks. You could even upgrade the cam later if you wanted a healthier power curve and still have room to grow with those heads.
A solid foundation. Wish I would of bought it when I did my H/C, difference was I only planned on swapping the cam out, and broke a rocker bolt off in the heads and used it as an excuse to upgrade to 799s.

One of the original test cars for the CheaTR is an 04 Vette A4. With a set of ETP215's that car routinely knocks down 28MPG hwy. I've never seen anyone complain about mileage with a CheaTR package. Stock idle and MAP values with 100RWHP gain... but I guess if you keep your foot in it, you'll see poor mileage everytime...

Well, I bit the bullet (and the wallet) and ordered the AFR 205s milled to 62cc, and cheaTR v.3 cam, along with a FAST 92/92. Cant wait to get this project started! Big thanks to everyone for their opinions, and Shane @ Thunder for answering all my questions and hooking me up when it came time to order Thunder might now always have the cheapest prices on everything, but they care and really want to help, and to me, thats worth more than a few bucks!
