The Stealth II 224/220 116LSA is a good street cam but (as usual) it requires certain parameters (mods) to really shine.
Things it likes:
1- Higher compression (11.2:1 is great)
2- LTs and true duals or LTs with Y and cutout.
What it will give you:
I went low 11 seconds in my A4 (stalled), with cats @ 120+mph
Drawbacks IMO, while having great midrange Trq, it lacs top end ooomph. It reaches a plateau and just carries on. It is a 4000+ rpm cam.

Predator hit the nail on the head.
IMO, you don't need to go tiny for good idle quality. I just installed a Comp XFI lobe 224/230 115LSA camshaft in a customers Corvette, and I had to lower the idle speed down to stock to even hear the cam. At 800rpm, there was zero indication the car had a camshaft in it, minus a slightly louder (than stock) valvetrain.
Thanks to new lobe technology and great tuners across the country, going rinky dink on camshaft duration to achieve stock driveability isn't necessary anymore. All you're doing going that route is leaving what you could have had on the table.

Could someone explain the pros and cons of the MTI Stealth II versus TR CheaTR V3? A reputable source once told me the Stealth II was a reverse split and not good to run with nitrous or N/A, not sure I believe all that but nice to get some second opinions. Sorry about the

As I'm just beginning to understand duration, overlap, ICL and LSA, could you explain why my friend said a reverse split was bad? I'm veeerrryyyy torn between the CheaTR and Stealth II.

IMO, consider going with a single pattern cam, like a 220/220 114lsa, 222/222 115lsa, or a 224/224 116lsa, they'll all run a smooth as the CheaTR without the wide split you don't need.
Any of the sponsor can get you a custom variation of one of their regular cams with a slightly wider LSA.

Thank you for the explanation, sounds like a custom grind is the way to go. For me at least. Sorry OP, didn't mean to highjack but it would seem we are travelling a similar modding path.

From my experience of running the MTI Stealth II 5 years ago on stock heads it worked great as they don't have as good an I/E flow ratio(went 11.5 with that set-up) Then switched to ported heads(went 11.2) but the head flow didn't favor the reverse split even with the compression bump. So I custom ground my own Stealth/Cheater in November 2008 before the V3 came out which just so happened to be almost identical. Anyways new cam picked up power everywhere in the rpm range and went 11.0 and fools everyone thinking it's just got bolt-ons. So it depends on the combo, feel free to call me to discuss further. For the record, I'd suggest the GT2-3 before the LS6, but a custom grind would be even better of course.
