That and also driving it up on ramps to where the front is off the ground a bit helps too.

I guess that's what happens when you have a LS2 with LS3 heads and a PCM that thinks it is controlling a LS1

Very nice numbers. Similar setup as mine minus the flycut pistons.

They just do not work

They don't do well on 4.0 bores

Congrats, very nice

What headers and are you running cats or cutouts?

lol

There is no doubt that the LS3 heads make power. The added bonus is that they work with 4" bores, and leave tons of room for cubic inch expansion. I made 470 at the wheels with heads that, aside from milling .030", are untouched. So, instead of having a maxed-out ported cathedral that will need to be replaced when I do decide on a stroker, I have heads that are ready to be ported to the set-up I select when that time comes.

As for the headers, they are Kooks 1 3/4-1 7/8 stepped and catted midpipes.

I'm attempting to garnish all I can to finally find a cam combo that works with proven results with these heads used on 6.0L blocks. Much like the golden child of Texas Speed, the 228R. It was a go to cam that has consistently proven itself and that's why it is so popular.

With this combo, such a cam is still a mystery. There are so many options and so many cam guru's and vendors and shops all have what they think works best. Which, let us be honest, makes the waters fairly murky. There are some of us who have a hard enough time understanding cam specs in general, let alone discerning how it all correlates together other than Uncle Johnny said to run this one cause it would make madz powaz! Again, I want to revisit the core aspects that this thread initially visited in the first place, but with more understanding now. There has been a lot of trial and error through out the years of what worked and what didn't. So what does that equate to now?

In the early days of this combo, you would see cams with massive splits, no doubt as you can see on the first page of this thread with dyno number spread sheet. But it's almost counter productive to have such a massive split and tons of overlap with these heads (reversion). Sure you gain some top end power and your power band doesn't nose dive off a cliff. However, what is this worth to you in comparison to drive-ability, comfort, and fuel consumption.

As such, from what I've read and experienced with a traditional split, 4 to 8 degrees is about where you want to be with this setup. This can be found in grinds from EDC to TSP to various other shops as well.

LSA typically hovers around 114 degrees as well. There are some 115s and some 113s and very few 112s. Again, this also ties together into the power band and where the timing events take place, all in the effort of keeping overlap down. Anything from +2 to +4 advance ground can be found in any of these combinations.

As far as cam specs that work well with this car, it seems to be hit and miss sometimes, but I have noticed some reoccurring key factors in this equation.

I've read SpinMonster's threads over on the Corvette forums with impressive numbers put up with a 230/234 0.612/0.598 114+2 cam (XFI/XER lobes respectfully), one still has to consider the weight of the GTO. This cam retains most of the low end power, but I still don't think it will benefit the GTO as well as it does the Corvette. I'm almost tempted to try it. A cam bigger than SpinMonster's I feel would have diminishing returns. You give up too much in the bottom end while not gaining much more in the top. And let's be honest, other than the serious track goers, most of this rarely visit the sky on these motors on consistent and constant basis.

I opted for the 224/230 113+2 due to the low overlap and ease of drive-ability given the car is an auto. There are many people running this cam profile. Beachgoat put up great numbers with this cam before he went with a stroker motor. My profile uses a 224 XFI intake lobe with a 230 LXL exhaust lobe with 0.609 lift on both ends. With this cam and milled heads/thinner head gasket, It's an absolute torque monster. It runs well at the track as well. I do have to comment that the top end seems to fall off a little more than I would hope it would, but it was expected (6300-6500rpm). I'd recommend this for a DD.

The XFI lobe is a quick fill lobe that is fast off the seat with moderate to high ramp rate. It's no LSK lobe but still fairly aggressive, even against an LSL lobe (slower off the seat with a high ramp rate after that). I've seen various vehicles with an LS2/LS3 combo and utilizing an XFI intake lobe put up great numbers. And it shows in the GTO as well.

Then I have noticed there is this magical 227/235 combo that seems to be the sweet spot for these cars. With an LSA as low as 113 (+2/+4), you maintain low enough overlap but still have some extra breathing room for up top for after peak HP gains. The torque still seems to hold it's own fairly well to get this heavy beast moving while still providing great mid to high end power. There are several guys using this cam profile with an LSL intake and exhaust lobe. These are comp lobe profiles and obviously Crane and Lunati profiles differ some but the 227/235 0.6XX/0.6XX 114 (+2/+4) profile seems to unanimous between cam manufactures, shops, etc.

So, that being said, I've concluded cam intake duration's of 224 to 230 with a proper 4 to 8 degree traditional exhaust split and 0.6XX lift seem to be what these cars really like and all perform well with. If you go with comp cams, the XFI and LSL lobe work best for an intake lobe. I'm curious to see if anyone would like to chime in on a consistently great performing exhaust lobe for this combo. The exhaust runner is not that weak on these heads regardless of what initial beliefs were.

What are your guys thoughts on cam profiles for this setup?

Using lsl lobes for both intake and exhaust here. My thinking is the same as yours that a mid 220-low 230's duration cam works best with these heads and the weight of the Gto.

I don't think there is necessarily a right or wrong.

My only input is the best "no brainer" way to go for results is a traditional split cam (high 220's-low 230's, high 590's-low 600's) with stock milled heads...ie my old setup, torquer 2, etc.

Different cars and parts respond different ways....I've seen many people (not necessarily on this board) with L92/LS3 specific cams that were disappointed...I've seen people with ported heads disappointed...Then I've seen cams that are "totally wrong" work really well...

I've never seen anyone disappointed with what I stated above.

why did you change setup's if the torque 2 was good. what numbers and times did that set up produce? did you have to fly cut the pistons with the torque 2 and what did you mill the heads too? I am looking at a ls3 head swap now. tks

Lol...I didn't change set ups..I changed cars

Only 1 person I believe has run the torquer 2...made in my mind some impressive #'s...M6 car...with pacesetters and bone stock (not milled) heads the car made around 460/415...with a real set of headers and milling the heads the car would have easily made 480/430....

i have a set of ls3 heads, intake with fuelrails and 42 pound injectors. i am planning on link bar lifters and mill the heads 20. i need rockers and stands. what gasket thickness would anyone suggest? i would like 11 to 11.5 compression. i am also looking at a torque 2 cam. i am running a speed density tune so i don't need a maf. any thoughts or suggestions. tks

If I'm not mistaken, milling the heads 0.030" and factory Ls3 head gaskets will give you 11:1.

10:8-10:9 ballpark .030 mill w/LS3 headgasket

closer to 11:1 with .040 cometic and .030 mill

I order them direct from Cometic.
From cometic's site, you can hit Shop and it takes you to this SEP place that is their whole product line.
Took about 10 days to get last set I custom ordered...and pricing is as good as anyone online. I ordered 4.100 bore x .036 thick for a 418 stroker

I'm glad you posted this. I was going to put some thinner gaskets on this summer and switch to E85, and I was wondering, whats a safe, tight quench distance? I was leaning towards a set of .035 x 4.100. My compression will be at 11.7:1.

I put the .036 on with pistons that were flush to .002 below deck. If your pistons are proud you need to be careful.
I'd really want to know how much above they are at full rocked, and what they are at pin c/l and then order the gaskets.

My pistons are flush with the deck, and dished so my quench area is really compromised vs a flat top piston. It never even occurred to me when I built my motor.

Texas speed does. 4.080 bore and 0.040 crush thickness. I used them in my build and did use copper spray. I haven't had any problems.

I had my LS3 heads ported and milled, and used a cometic .40 gasket. The car put down healthy numbers on the dyno (462/444 locked SAE) and the butt dyno is happy lol Haven't been to the track but Im anxious to see what it'll do with the stall, gears and sticky tires (if the rear end holds )

nah your quench pad is still there on the piston, mirror of the flat part of the head. The dish is opposite the chamber side.
if your pistons are 0 deck and they don't rock more than say .018 or .020 then a .036 thickness should work ok. If you have some larger bore clearance or due to the skirt design it rocks more..then I'd leave a little more room
