Smart. I went back and forth with him a bit on mine and he finally basically yelled at me and said it will be perfect. I wanted something a bit bigger. I must say, the cam works spectacular. My car makes quite a bit more than anyone expected.

The cam Pat G recommended for me was considerably bigger. The hardest thing about getting the "right" cam is a lot of times people don't really know what they want or at least how to describe what they want.

Pat G works within the boundaries that YOU set. You tell him what you're using it for, how you want the idle, shift rpm, red line, how much lift you'll tolerate, etc. You won't get a big wampum destroyer cam is you tell him it's going to be used on the streets and you want a stock like idle. Goes the other way too. If you tell him you want a street/strip cam with chop and lope, you won't get a stealth cam.
For someone not knowing what the hell they want or how to get there, he's a really good option.

I wish people would post dyno sheets for the cam they installed to quantify the size vs reward aspect of various cams. When we see that the difference in power between the biggest cam vs low overlap cam is only 8hp, few would buy into the bigger split is better camp.

Yeah, that's a lot of camshaft for sure. I don't think Mitch used the word stealth anywhere on Pat G's order form for that one. If memory serves, I don't think he saw more than 10psi either. Top to bottom, that's pretty impressive power on very mild boost.

Instant gobs of torque. I've Learned how to roll in to in 2nd and minimize wheel spin. Ramping it up, and by ~5,000 RPM's I'm WOT wheel spin minimal when running R888R.
Yep - 10 lbs boost max. 8-rib I replace the stock tensioner maybe every 10-15k miles just cuz..
Rodney - in your neck of the woods, I hear any less 1,000 WHP ain't squat. Here in Ca I'm hot ****, LOL
Stock LS3 (they are rebuilt Texas speed ported heads, so they likely shaved them to straighten them up, so maybe a tad higher than stock?
They set the limiter at 7,000. I'm good with that, and even try to not bump the limiter (1st second and 2nd are quickly done, I do bump it more than I should [even while using Rodney's *family relative* theory])

Yep! I had Pat G do 2-cams. One stealthy'ish, and one not. I picked the one not. With no cats and 2: headers and 3" exhaust, I like the way it sounds...

For me, it's performance, valvetrain life, choppy idle, then tunability/drivability as far as the order of compramise when thinking about cam specs.
I've read many of your posts Spin and guys like you make this forum great btw.

Those Houston boys do run some crazy power. WAY out of my league though. Last time I was at LMR, I heard a twin turbo Vette leave the shop. Sounded glorious! They said it was well into 4 figures power wise. With me having trouble keeping a single turbo diesel pickup between the ditches....I'd best leave that twin turbo LS stuff to the youngsters

So, what did Pat G recommend for the stealth cam?

I have had multiple cams spec'd for my build and usage... Some close, some very different to the point I am less confident with choosing. I added the overlap numbers at the end. I was surprised how much more aggressive LME was.
