Old Man Cam - dyno results
The reasoning behind this cam was to retain the stock idle sound and quality, but still make respectable power and not sacrafice any driveability.
The customer's car had the following mods:
2000 Trans Am, 6-speed
-Whisper lid
-ported MAF
-TR ported TB
-Hooker longtube headers w/ off-road pipe
-cutout
-LS6 intake
-stock rear w/ 3.42s
-ASP pulley
The only changes were the addition of the old man cam (Comp 918s, Ti. retainers, TR 7.400" pushrods) and an ASP crank pulley:

Specs on the old man cam: 214/220 .602/.527 115* (2 degrees retard ground in)
We were a little concerned with using the Comp 918s, but they worked extremely well. We were hoping the new Comp dual springs that fit in the factory spring pockets would have been released, but they are still in testing.
Overall, we are pleased with the results! The cam is still using stock tuning and stock TB hole and doesn't even try to stall. If you don't listen close enough, you would never even hear the cam, even with the cutout open. Through the catback, it is totally undetectable.
We will have a more of these cams in stock early next week if anyone is interested.

<strong> That's pretty good for no ls6 Intake.. </strong></font><hr /></blockquote><font size="2" face="Verdana, Helvetica, sans-serif">Vince, the car already had a LS6 intake installed.

Just because 918s are holding now doesn't give me confidence that they will hold 8,000 or 12,000 miles from now. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" /> How is the valve train noise?
Any thought about a midsize cam based upon that design, maybe a 220 intake with a 600 lift and TR's 224 exhaust lobe with a 114 LSA?
Anyhow, just curious. Thanks for the info.

These were LS1 heads.

I feel the 918s will work fine. Regardless, you should replace the springs once a year with almost any aftermarket cam. The cam is definitely going to be hard on the springs, but the 918s are up to the task.

I don't intend to even look at replacing springs until I get around 30-40K on my 26918s, this will take me about 10 years to hit LOL! I have a B1 cam and the car does not really see much drag strip action.

since these worked good with stock LS1 heads.......would it show much improvement with a good set of heads?
<strong> We have had very little experience with the 02 LS6 cam. This is going to change in the near future though, as we are planning to swap it in a f-body very soon.
