Cam questions *die horse*

Thanks Sport.
Who makes those cams btw?
I wonder which side I'll be more restricted on? Since the heads flow better on the intake than exhause but I have a stock intake manifold and will be putting TOG headers on, it makes it kind of a toss up.
Wonder how that reverse split cam performs, know anyone who uses it?

Eh, I just made those specs up to show the intake vs exhaust crutching. The old, reverse vs. standard stuff.
Guy named Ed Curtis can grind you ANYTHING you want however.
If you want a 226/220* .59/.56'' 110/110*, he can probably do it. He has a ****-load of lobes available in the 220*+ size @ .05''...
Our heads flow fairly decent on the exhaust. About 80% in stock form. Then, strap on the intake and we're looking at 83% or worse. Higher you go, more intake crutch you add. The EFI intake manifold plays a large roll in the sorta cam you need... obviously since it is such a restriction.
Notice how all of the 'large' cam setups still seem to peak at 6200-6400rpm w/ a LS1/LS6 intake manifold? So, when you go larger with a cam, all your doing is boosting the higher scale of that range (1000-6500)... Your wasting lobe practically.
I know of one guy using a reverse split with a truck but, I'm not entitled to say who and he doesn't have any solid results yet. I know of a bunch of F-body guys with these cams. All have very 'flat' and broad torque curves.

FWIW, I have a LQ4 and called cammotion, the specs they came up with are 223/226 .576/.574 on 112 +4*. I started with a 3000 stall, and loved it. I just fried another trans, but till then, I had a TB stall, and it was just about right. Personally I wanted a little more stall, but I think if you started with teh TB instead of something bigger it would be fine. I kind of want to go bigger now though 
Just hate to loose the low end for when Im off road.

Yup, I'm gonna see good you are.
Just bought a TR 230/224 .575/.563 111 LSA from a member just the other day. Still won't get it in for a while, waiting on my ARP mains to come in and need to pick up misc crap before I can start bolting it all back together.
