Very cool patrick.
With the real gains not kicking in until 4000 and so much extra power above 6000 rpm, it would be cool to see Thunder try a cam to move some of the power down into the daily driver range. For a stock bottom end daily driver, I would like to see a cam that was done around 6400 rpm, not 6900. I wonder if you give up 4* of exhaust duration and cut the LSA to 115 whether you could make it a little more peaky in the midrange, especially if you add 1 or 2 degrees of advance. That would not change the overlap and keep that same monster intake lobe.

Wow, props to Geoff and PatrickG!
This is what I have been waiting for since the first Old Man Cam discussions on the old LS1.com board from 4 or 5 years ago. Stock manifolds, a cam ground with a restrictive exhaust in mind, capable of idling the car uphill in a parking garage with your foot on the brake at 800rpm. A perfect package for those of us who think the car is loud and rowdy enough with stock manifolds/cats and don't want to increase noise or reduce ground clearance with headers!
I had been thinking 402 LS2 stroker as the next mod for my 125K mile Z28, but I may need to have Thunder incorporate some of this cheaTR cam approach.
I wonder what this head and cam package would do with 402 cubes instead of only 346?

Patrick:
The below 4000 rpm range looks much better on this graph (Jason's car with stock heads) compared to the result you achieved with your AFR heads. On Jason's car above 4000 rpm, it also doesn't open up as much as on your car at 4000 rpm.
This does look good for stock heads, but I'd love to see your AFR heads with the Cheaterlite.

Yes, I just got my air compressor as an early Father's Day and think the first test will be installing this cam. Are the patriot gold springs a better choice for this cam. Doesn't seem like the 918's quite cover the lift. Any drawbacks to the patriot gold springs? Are they a direct replacement on the stock LS1 heads? Aka, no modification to the seats or heads ( I don't really know what I am doing)? Is the gasket set that TR sells have all the things I need to make this happen besides tools and lubricants. Thanks,
Jim Kay

Go here...
I personally wouldnt choose the CheaTR cam if you are not trying to sound stockish and since you already have LT's then why not get something a lil bigger...

I just dyno'd my 00 c5 with cheatr cam and tea 5.3 stage 1.5s. I got 372 rwhp and 355 ft lbs of torque. I also have an asp pulley and vararam intake. stock z06 full exhaust and ls1 intake. I dynod 330hp 340 ft lbs with my vararam. I think my 4.10s are skewing hp and torque some though too.

Is your vette a 6spd or auto? Those numbers seem a little low to me especially if its a manual car.. Granted a good exhaust setup and intake would probly yield another 30rwhp or more..

Futral Motorsports has the F13 & F14
TSP has the 231/237, 233/239 Rev2, 235/240 Giant Cam, MS3 etc
LG has the G5x2, G5x3, etc
Thunder has alot of other good cams besides the CheaTR cam
So there are alot of cams you can choose from.. Just depends on what kind of manners you want it to have and if you plan to put a set of heads on it later..

Well, I'm going to try this cam on my RX7 with a set of JBA Shorty headers, 2.5" custom y pipe, 3" cat-back w/ straight through muffler, stock cats and some old school MMS Stage 2 heads milled .030 (285 ish intake).
Will also be with a ASP pulley, LS6 intake and ported TB for bolt ons.
No longtubes available for my car right now with an automatic trans so I figured I'd try it out.
We'll see how well it can do in a much milder configuration.

i have been eyeing the cheatr heads and cam package for some time now, but i have not heard of any automatic guys coming foward to praise it, it is very tempting to try it out, damn the smog *****.

Stay tuned for numbers from a 100% CARB legal P1SC ATI setup.
I just put CARB legal JBA coated shorty headers and the factory Y-pipe and cats back on (sick of worrying and dealing with smog).
My goal is to still be over 550rwhp with the help of a 50 shot, or whatever it takes on top of 10psi to get there.
