Both r DD however the CheatR makes good power with stock manifolds. I would recommend the CheatR if its your DD however it idles 99% as stock and nobody would figure out that you r cammed. Makes also good power between 20-40 rwhp with stock car.

The Cheatr cam 214/230 .601/.578 117 LSA works well on an otherwise stock car.
It seems like alot of lift, considering the level of performance this cam achieves, and with that duration (214 intake), would this not be a considered an agressive ramp rate? Why not go with something like a TR224/224-114 cam? They can be very street worthy, and they make great power over a wide range. 224/224 .563/.563 114 LSA

I agree it will idle and drive like a stocker, just go with a good set of dual springs or at the min some comp 918's and titanium retainers. For the price though you cant beat the PRC duals in my opinion.....

It seems to me that the choice is this - if you're going to stay with stock manifolds, the cheatr will give you the best power and be very driveable with a minor tune.
The old man cam will give you a little less power but should work well with a stock tune.
Both will be fairly rough on the valvetrain, so 918s or better are a must.
For more of a daily driver with a little less power but much easier on valvetrain look at the 212/218 or 216/220.

with the cheater cam id be worried about the high ramp rates
with such high ramp rates its like the cam just pounds the lifters, pushrods, rockers, valve springs and valves... if you want to go cheater deffinatly have some GOOD valve springs, id recomend double coil...

Which cam is best depends on the goals you want from the cam. You can look at this thread from another point of view:

I am using the OMC cam in my daily driven truck. I have over 30,000 miles on the same set of valve springs. The truck runs just as good today as when I put the cam in it. The only maintainence has been regular oil changes.
Although it is counter intuative, putting more lift in the cam due to the fast ramp rate actually makes the lobe MORE stable. This lobe is perfectly streetable and will have a decent lifespan.

Which one of your cams would you consider a good choice if wear and and valve train stability were the chief concern. Would you say that the TR224 cam is a better choice than the OMC or the Cheatr in this regard? Or maybe my wear concerns are unwarranted and the difference is insignificant.
I like the the performance of the TR224 but I also want a cam that is easy on the valve train. (I don't want to be wrenching on this part of the car again any time soon.)
Thanks!

The TR224 uses softer ramps. As far as long term durability is concerned, I think the difference between the cams is not significant. The OMC or the Cheater would be better served with a double valvespring but only to help them RPM better. Either cam should last quite a while with the proper spring setup.
OTOH, the TR224 will definitely give you a little better torque in the lower RPM ranges as compared to the Cheatr, but it won't RPM quite as well. The 224 also will also lope slightly harder than the Cheatr.
Both are good cams, but they are meant for different things.
