LS3 to C6 ZO6 level
With a dry sump Grand Sport LS3 6 spd man trans 2013 coupe. I don't want a blower and the weight on the front.
What heads & cam or cam only with long tube headers? I would like to hear about your build more than just your opinion.
Do you have a heads and cam package from someone lie TPIS, that one put out 580 HP I think.
Don't want a crazy cam, but really, what will work best?

Great question! I have the same question. Would like Zo6 power w/out going the forced induction route. Thanks for posting this thread.

I had all the bolt ons and a 226/234 114 cam in an M6 LS3 Coupe. It made about 475 rwhp. That's more than a stock Z, but you will need more to keep up with one since you're going to be heavier. That's a long way from a big cam, but still didn't have my idea of perfect manners. Not bad, but not the stock like manners that some claim for cams that size.

you'll make Z06 power on an LS3 with headers and a CAI. 440rwhp/450tq on my '13 A6, which is toward the low end of the Z spectrum but still in there... on a stick shift with a dry sump you're probably looking at more power and less torque. A good tune is the icing on the cake, and lets you enjoy all that power without destroying your tires or drivetrain.
If you mean ZR1 power, that's a different story. I haven't done h/c/etc. but a good h/c package and maybe a bit more displacement should get you right around there.
I'm running Pfadt 1.75" LT's with HF cats and a Halltech MF107 intake, along with a 160 'stat. New mufflers going on next week but that won't impact power at all.
For reference, my car made 366/380 (RW) bone stock.
headers and an intake will also put you above a stock stingray, if you're into that sort of thing.

According to my shop, I had one of the lowest baselines and highest post installs of any LS3 they'd seen.
To be fair, the temperature differential was pretty large. Definitely a huge SOTP boost!! (still not loud enough though hhahaha)

With the trick flow head & cam kit and a good set of American Racing headers and good tune it should be possible. With good intake, breather, maybe a ZR1 Katech clutch and a few other parts very healthy streetable. You think??

100 plus
i have a 13 gs 6spd. car was strong to begin with 403 on dyno (i know, dyno numbers are all relative) as its a dedicated track car, contracted w jeremy at horsepowersales of florida, installed a comp cam package, lg longtubes and cat delete, 160 stat, vararam cold air and full tune. car did 511 with fat tune (track car, tuned for high speed) car regularly pulls away from "supercars" that begin with F and P . admittedly cam's a little big for street, but a little less would still make close to 500 rw

12 GS M6 with LG6x3 cam, LG long tubes with cats, stock NPP and LG CAI. Car made 440hp on my Buddies Mustang dyno went 10.9 @ 125 with Dr's all else stock. Like to get it on a dynojet just for comparison sake. Car runs good, but you can feel the cam below 1500.

We have so many options available the real questions are budget and tune availability.
We have tuning options available that we can progress through if you are working in phases or we can drop an entire 100HP+ setup at your door.
The GS is such a nice concept and idea. Most of the goodies off the Z without the price tag. coSPEED likes em so much, he got one also! Although it only sees the light of day for 6 months at a time. Such a shame.
We can get you every little and big piece you need and then finish it off with a complete customized tune from start to finish. And we can even get the most out of any steps you take after that also.

We talking stock Z06? Just bolt-ons will get you to the low range of a stock Z06. I ran 124 MPH in great air with intake, headers, ported TB, and tune (base M6). And I have a few more tricks up my sleeve to add about 20 more rwhp on pump gas. So 450 rwhp (which is what a stock Z06 drops) with all the bolt-ons is doable.
Not sure what that comment about not matching LS7 torque is about...you can surpass stock LS7 torque with bolt-ons while only revving to 6500. I haven't seen the torque curves overlain, but I would think a bolt-on LS3's torque curve comes on stronger earlier.

But IF you were to want to get some heads, we have so many options. CNC'ing yours is one of the most common options. Or getting a set already cnc'd. There are a few new offerings out for the LS3's in terms of heads. One of the more talked about ones are the Trick Flow LS3s. They can make some serious power. The other options get quite a bit more pricey from there. The LS3 and its components are VERY versatile and robust. They will take and make quite a bit and surprise alot of people.

C6 of Year Finalist (performance mods) 2019
If you're talking 1/4 mi times, then go to the Performance list in the stickies and compare it to the Z06 Fast list.
Number of cars with PB under 11.000
LS3 Bolton - 3
LS3 Internals - 11
Z06 bone stock w/stock tires - 1
Z06 bone stock w/DR's - 9
So unless you're comparing dyno sheets, you can look on the Performance list to see what mods were used to produce enough power to run a LS3 relatively even with a Z06.
It's no guarantee the mods will assure success, but they will make it a driver's race instead of a more likely Z06 win.

I have a 2010 M6 GS and finally got to run a bone stock Z06 last weekend. from a 35 roll I put a fender on him and held it off until about 70 when we had to shut down. we were both surprised.
we then ran again on the highway from 60-65. He put about a car on me quick and kept pulling. I was not in a great gear to start but he still pulled once I did get in my power band. I have 1-3/4 pfadt headers and halltech mf103 intake with a custom tune. Car made 416/434 on a mustang dyno.
I have thought about a cam because its also my goal to get z06 performance with my GS. I just don't want to deal with a cam for my daily driver. I am either doing a 150 shot of nitrous or save for a blower. I am leaning towards a plate system because I don't race very often and just want the occasional bump in power.

You do not have to get such a huge cam to make parking lot driving a disaster. With the requisite list of tools needed you can change the cam in a weekend.
If you get our HPT/tune combo, you can have it running 100% in that same weekend...given some spare time of course.
