LS2 build input - CAM/Heads

[Nemesis RR]

all those cams are to big and power will not start until after 3000 rpm. I would look at texas speed for suggestions. Just an opinion for more overall power.

How do you plan to use the car, and what are your HP goals? What suspension setup will you be running, especially in the rear? Mini tubbed? Don't want to overbuild the motor for the car. Sounds like sweet build you have planned.

Thanks guys.

Good point on the LS6 intake. Now that you mention it I do believe I have that in the back of my mind somewhere.

The car will be a hot street car, Pro Touring build, and is getting a full tube chassis and C5 drivetrain w/IRS.

My HP goals... 1000+ would be fun!!! But I'm thinking ~500-600 with decent low end TQ.

I stumbled across a Popular Hotrodding article after I posted this, and they did a good build and ended up building 572HP @ 6500 RPM, and 504TQ @ 5100RPM... that's about what I'm looking for!!

By the way, TQ came on at 434ft.lbs at 3000RPM!!!

Here's the link, and I'll definitely follow up with Texas Speed and LS1-Tech.

Thanks again!

Okay... slept on it, and then woke up thinking... What can I do with the stock LS2 Heads?

Can I achieve some reasonable HP/TQ numbers and not have to go the L92 head upgrade route?

That would save some dollars (that obviously just get spent somewhere else on the car!!!... )

Does anyone have any good Cathederal head setups?
What CAM did you run?
What Head/Drivetrain upgrades did you have to do?
What HP/TQ numbers did you end up with?

Any imput would be great!

Realistically with stock heads and and LS6 intake , good cam you could probably get around 425 HP to the wheels and somewhere near the same TQ . However add a 76mm turbo and you could make 600 to the wheels easy.

[SoCal_63 SS]

Ya, no kidding... and the STS turbo setup probably isn't much more than the full L92 setup by the time your done.

Anyone running a turbo on LS2 Cathederal Port heads, and if so what did you have to do to them??

You should get in touch with EPS they can custom grind you a cam for about the same money as an off the shelf unit. They are good and have cams in some of the fastest LSX motors in the US. Engine Power Systems www.engpwrsys.com

I recommend Texas Speed as well. I bought a 408 iron 6.0 short block from them. Told them the heads I were going to use (L92 of course) and they told me what Comp Cam to use and the appropriate head gaskets for my desired application. Great guys to work with.

Hey guys!

For some reason my notification turned off (or maybe I didn't set it up??!??? )

Thanks for the good information. It would be great to maybe put together a list of LS2 specs from everyone. Then over time a User could sort of pick what they were looking for as far as end result and then copy the build...

Here's mine:
Intended Use: Street/track, Pro-Touring build
Engine: 2007 LS2 (TBSS motor)
Crank: Stock
Oilpan: F-Body (Pace Perf: PAC-8771)
Heads: L92 (Scoggin Dickey: SD8801-1)
Intake: TBD - LS6 or F.A.S.T or Holley LS 92mm High Ram
Compression: ~ Stock 10.6/1
Cam Specs: TBD
Idle Quality/RPM: Lumpy!!
Fuel System: TBD : Aeromotive Stealth A1000 cell or similar build
Max HP: TBD : aiming for 500 range
Max Tq: TBD : aiming for 500 range

I just called Texas Speed this week and would suggest you do the same.

I am planning on installing the same setup LS2/4L70E out of a Trailblazer. They recommended a 228R with 114 LSA with stock heads and and LS2 manifold to keep the powerband in the lower rpm range versus the upper if you go with the L92/Ls3 heads. With good headers, ls2 car intake, good tune and the recommended cam you should get you over 500hp. This cam is mild so a bigger would yield better results.

Here is a link to the cam http://www.texas-speed.com/p-1158-te...pring-kit.aspx
