OK, I am officially a huge fan of L92 heads after seeing this combo. Customer has an immaculate six speed 98 Camaro that he road races. He wanted a motor combo that would make strong power under the curve, not just at peak. He sourced a low mileage 6.0L LS2 out of an 2005 Vette, then added some stock L92 heads and LS3 intake manifold w/90mm TB and stock MAF. The exhaust would be 1 7/8" American Racing headers with dual cats. He wanted a custom cam to match all this and emphasize power in the mid-range:
The cam is a 223/231 .610/.617 113LSA +4 advance using Comp LSL lobes and Patriot Extreme dual valve springs. As you can see, the combo worked amazingly well.

How much would the graph numbers change ?

Pulling up an older post here but curious to here some input from some of you guys with LQ4 motor building experience. I know dyno #'s vary a bit but here's my setup and what I saw for RWHP and RWTQ
LQ4 .030 over
Stock dished pistons
L92 heads - Shaved around .030
Comp 228/232 .591/.609 cam (can't remember LSA, think it's 114)
FAST 90mm throttle body
LS3 intake and injectors
1 3/4" long tube headers w/ 3" exhaust (no cats)
On chassis dyno I saw 430 rwhp @ 6200 and 396 rwtq (gotta look back to see what rpm)
In my mind I don't think low is end power is overly great. But motor really picks up at 3000 rpm and up. Thoughts on cam size?
Curious to here thoughts and opinions on this combo, what could be better? I run the car on street and road course events.
Thanks!

As for exhaust, 1 3/4 ok but 1 7/8 be optimal. 3 inch exhaust CHOKER. Need 3.5.
At least change, start with, upgrading to a flowmaster y pipe merge mod and a free flowing, straight flow 3.5 muffler.

Gotta love this site
1st. Thanks to all who have posted. Especially Patrick. You the sh*#.
I am on my 2nd ls build. 1st I loved 87 suburban with 40s getting 17 mpg. I found another project. An wifey says I can only have 1 suburban. So I took a great well known friend for a ride an well he know owns big black. Great white my new build is gonna be sick (I hope). I got it in December an put It in storage till I get back. Got all black leather interior already, Dana 60, Eaton rear for back. 205 Devorce mount . Oh 513 gears. Lol. Yes daily driver .
Also have a 6.0 going 30 over, 821 head not sure if I am doing 5 angle Valve job after reading this , Msd atomic intake an nick Williams 102 mm drive by wire throttle body. I am really interested In this cam. How do you think it will work with my set up? Please keep in mind. I have accumulated so much stuff in the last year. Motors , 4.8, several 5.3 , an a l33 , an a 6.0. Good heads an not so good heads. Drive by wire an cable car an truck intakes. .
Any help would be greatly appreciated
Thanks

Good morning. Ui know this is an old tread but i have nearly this exact combo but i got only 392rwhp on a dyno jet and my track mph back it up. At .050; 224 232 .629 .608 115+3 -2 degree overlap. Lq9 .015 milled l92 .040 head gasket for 11.2 comp. Btr springs l92 intake 1 7/8 headmans to 3.5 collector to 3" to the rear with x pipe 4l60e with 2800 patc converter with 3.23 gear 4" cold air wth maf. My tuner say that what it should make. This thread makes me say different or is this correct with the installed cam
Here is the sheet

[QUOTE=my406cid;19316207] Are your heads stock besides milling? I have a very similar cam to you. Mine is 224-230 .588/.571 115+3. The rest of the mods are in my sig and i make 494rwhp and 500rwtq. There seems to be something up there with your combo. I'm only .8 liters more displacement than you but am making 100hp more at the tires through a power sucking drive train as well.

Are your heads stock besides milling? I have a very similar cam to you. Mine is 224-230 .588/.571 115+3. The rest of the mods are in my sig and i make 494rwhp and 500rwtq. There seems to be something up there with your combo. I'm only .8 liters more displacement than you but am making 100hp more at the tires through a power sucking drive train as well. Yes sir stock heads with tooly springs locks n retainers
