My cam-uneducated mind says Cam 1 for power, but Cam 2 for stealth, though Cam 2 has more 3* more exhaust duration, which could skew a bit of power to Cam 2.
Otherwise, to me, the tighter LSA of Cam 1 should give it a bit more peak power, while on Cam 2, the wider LSA gives it more stealth. Overlap is close between the two.
Just going on what is given so far.
Just for conversations sake..... fingers crossed.....

The biggest issue is bench racing on lobes you dont know what they are. I actually expect the livernois to be a bit like the lunati lobes in the ls3 test a while back and be a bit more robust in the mid range and upper rpm even with a supposed 117.5 lsa. icl would be good to know also, but with a few diff timing sets you can change that. Build a bit more cyl pressure with either and have a good amount of tq.

I got similar answers on another forum I posted that question on. Some thought cam 1, some thought cam 2.

The intake centerline lift on cam 1 is 113. That spec isn't listed for cam 2

In case anyone is interested, Livernois sent me this dynograph of the gains from their 1C cam in an LS3/G8 GXP. Gains look pretty good for a stealth cam to me.

413 HP for the "before" number is pretty strong for a G8 isn't it? Aren't most of those in the 360 hp area?

And it's nosing over by 6400. I don't know how high you want to spin it, but extending out the exhaust duration would still keep it stealthy but would pick up power above 6k, especially without headers.

Blackdevil77

That 413 rwhp is with exhaust, intake and tune, which is pretty much in line with what they make with FBO and tune. The addition of the cam brought it up to it's final number.

I'm fine spinning it to the factory redline. I just want a modest bump in power, no need to rev to the moon.

The graph is in STD so SAE would be 396ish to 400. That would explain the added power you see i guess.

The gains are throughout the entire RPM range, so I would call that a success for a "stock converter cam". That is what we aim for our on stock converter cams like the Torque Titan.

The Pat G recommended cam is in. He recommended me a 218/224 .598"/.598" 115 LSA +3. What do you guys think? How would this cam compare to the others I was considering?

with less exh duration it wont make as much power. But they are all about the same, you just pay $20 extra to him to give you what everyone else already said.

Blackdevil77

I kind of have that feeling as well, everybody kept recommending to get a cam speced by him so I figured I'd give it a shot. The +3 is interesting though.

Those cams have the same amount of overlap. They will sound the same.

Blackdevil77

Back to square 1 it seems. If the Pat G spec-ed cam would make LESS power than the Livernois 1C cam, but they're both "stealthy" wouldn't that make the 1C the better choice between the 2?

Would this make any more power than the Pat G (218/224 .598"/.598" 115 LSA +3) and the Livernois 1C? (218/229 .600"/.600" 117.5 LSA)?

This is a 217/225 .595"/.587" 114 LSA. At -7 degrees overlap, it should be fairly tame sounding, no?

G Atsma

At -7 degrees, a bit of lope; not much.

Get the 1c call it a day. you are getting too caught up on theory and numbers. youll want the biggest of the 3 anyway so just get it.

G Atsma

^^^^^ this^^^^^^^

Blackdevil77

Lmao thank you. A lot of the theories and messages I've been getting regarding the cam had me pulling my hair out. I'm sure you guys got as tired of the back and forth in this thread as I did. When you get inboxes saying "you're gonna regret going with that cam and not going bigger" it just makes second guess and look at other options. The result is "what about this? How about that? This?

Jimbo1367

Either the PatG spec'd cam or the 2nd CM cam. Did PatG say what core and lobes to run? I wouldn't hesitate to use whatever PatG. specs for you specifically. He does especially well on rect. port cams.
