Does anyone know the stock grind of the Z06 and has anyone tried any of the cams out their for the LS1 cars? From the flow numbers they posted in HITech the LS6 seems way under-cammed.Any info would be great.

I am not versed in the cam specs, however, DRM (dougrippie.com) put a cam in my car that retained stock idle qualities and made great rwt from 2800 rpms to redline. The curve is as flat as they come. Call Vaughn or Peter at DRM for the lowdown.

I'm running the ASA cam and GM CNC'd (by Lingenfelter) heads. Great power, but poor idle unless you bump up the idle speed.

Hey Dave!

Hope things are going well for your racing efforts.

Spent a fair amount of time with Danny Kellermeyer at the Birthday Bash. He's a great guy as well.

With that ASA cam and head work you must be in the 450HP+ range. Are you running the ASA ECM or a reprogram on the stock controller?

I never did receive that paperwork you wanted me to look over. If you sent it let me try to track it down. If you didn't, give me a shout on my e-mail.

Best of luck!

The cam specifications for the OE 01Z06 camshaft are posted at http://www.idavette.net/hibz06/index.htm

Need more power?
Use the 02 Z06 camshaft, valves, springs and calibration. Uh...when they're available. What are the specs for the 02?

The full story will be on the C5 Registry site at 00:00:01 on 6/20.

Also bear in mind that the ratio of the rocker needs to be taken into consideration when calculating the final lift numbers.

The cam specs for LS series motors look pretty bland until the multiplication of the rockers is calculated.

One nice thing about over ratio'ed rockers is the increase in ramp speed, or maybe better stated the velocity the valve opens as a result. It's a way to get a more "radical" camming without grinding a cam that would be hard on even a roller lifter.

Once again, the raw cam specs don't look exciting for LS motors until you do the math including the rocker ratio.

A "radical" cam will shift the torque curve to a higher rpm, not what GM wants in a streetcar. The low-end grunt is one of the things that make this a great car.

The LS6 cam is a compromise of fuel mileage, HP, low-end torque and emissions. True you can use a more radical cam, but at some point you have to ask yourself, is it a streetcar or a racecar? If your answer is "race car", don't just stop at the cam!

Jason:

Lot of good info here. You may also want to consider contacting Katech Enginering for help in answering your question. Their link is on this forum.

Thanks for all the info guys, I am looking at putting a combo together for my car, and dont want to spend $2000 for 20-30hp been their done that with my old TA. I finally got serious and spent 1k on a cam, rebuild, and I ported my own heads, picked up over 1sec in the 1/4. Anyway its just me. Thanks again for the info. I will let you guys know what elese I find out.

I went and looked at MTI's web site, With the LS1 head and cam package stage 1 they are at 391hp and torque went up to 366. They lost nothing on the bottom end. I was impressed. Even though the stock Z06 heads dont flow quite as well as the ported LS1 they are within 10cfm. If what I am seeing is right put a cam in and get 370-380 at the wheels not bad and probelly cost less than a cat-back system.


The dyno sheet shows an improvement from 299.6 maximum rear wheel HP to 391.3 maximum rear wheel HP (A 91.7 Rear Wheel HP Increase). Torque increased from 316.9 to 366.9.

I think someone previously posted the following;

'01 = .525"
'02 = .552"

I'm just going by memory though.
