116 Intake Centerline
120 Lobe Separation Angle
.330 Intake Lobe Lift

230 Exhaust Duration
116 Intake Centerline
120 Lobe Separation Angle

The cam should be on its way back from Cammotion. If there is anything else on the card... I'll be sure and pass it along.

This may or may not confirm whats been posted before but thought I would post it up anyway.

Thanks to Xtreme Motorsports in Tempe for allowing me to be a part of this project

Hopefully more info on the LS7 as our project progresses to completion.
Enjoy,
Bill

Do you have the entire cam doctor file? It could be used with some engine modeling software like Performance Trend Engine Analyzer.

I do not... call Cammotion and ask if they will send it to you. We will more than likely be going in a reverse split direction for a TT app. We just wanted to confirm for ourselves the grind of the factory LS7 cam for future projects.

That is a little baby cam..the car idles a 600 RPM and has no vibration at all..can't even tell it is running..you can use the new Z06 as a around town dailey driver if you want to ..a very docile car till you put your foot in it...now on the other hand put a 254\254 .630\.630 110 LSA in it and watch what happens...that a long with a set of long tubes and a good exhaust system with a custom tune and it makes 640 + HP at the crank all day long...

I knew the cam was small, but I didn't think that intake duration would be so tiny. Lift looks about right for a factory cam though. 120 LSA probably for emissions testing and drivability. I guess GM knew the heads/intake flowed well enough that they didn't really need a larger intake duration to make their goal of 500 hp.

It kind of reminds me of the CheaTR cam. Thunder didn't lie when they said they mimicked GM's cam design; however, I think the LS7 cam probably isn't as aggressive as the XE lobes or whatever they use.

I'm sure just a cam alone would add gobs of power. Some 1 7/8 or 2" inch headers and it'll really scream

A few of my customers have dynoed their bone stock C6 Z06 and they are making 455-460 RWHP..so GM is real conservitive on the 505 FWHP..looks like they are making about 535 FWHP give or take a little at the crank.
