Does anyone have flow bench data?
Looking for flow bench data from stock, and ported 55 cylinder heads. Please let me know if you have any data.
Also would be interested in data on Kleeman, and PTE cams for our platform. I am not sure if they come with cam cards, or not. I have the specifications for the Schrick cams, and would like to make some comparisons.
I am going to be tearing in to my spare motor this week. I will be measuring PTV clearance to see how much room We have for upgraded cams. I will have to weld a couple of lifters in order to get accurate measurements. Since there are no solid lifters for our motors available.
I would also like to see how much interest there is in getting a set of cams. I am looking to get fairly aggressive if possible.
Thanks

PTE is the one.

I'll help some. Stock cams .419 lift, kleeman cams are .451 lift. PTE are .473 lift. The duration are very similar on the stock and kleeman. PTE's are a little more aggressive. I've had stock,S/C heads and N/A heads all flowed and ported and the best head was the newer N/A heads. My N/A heads were right at 300cfm at .550 (had some .5xx lift cams made that wouldn't work like I planned). We focused on lower lift flow and maximizing the flow in that range. Blackbenzz and I found out the hard way that the older N/A heads are different than the newer ones (2005 and up I believe). The newer heads don't have the EGR hump in the exhaust port and have a bigger exhaust port plus the intake port doesn't have the large divider.

Thank you very much.
The more data that I can acquire will certainly help cut down on the time it takes to get the information to the cam builder.

I have been shot down by several companies. I have not heard back from a few others, but I am not giving up. I am also trying to source a company to do my heads as well. I have a long list of cam builders that I am working my way through. I am kind of surprised that none of them are willing to do something out of the norm

It's not that they're not willing to, it's just not economically practical to do small production runs on something like this.
It'd be different if this engines cams shared critical dimensions with a more commonly modified platform so that existing blanks could be used.

I understand this, but some of these guys have numerous MB cams listed that they build. Those are single engine family cams as well. Most of them are older but still MB cams.

Contact Web Camshafts. They weld them up and regrind them to keep your base circle. I used them on an older Mercedes engine and have been running them for about 4 yrs. I talked to about a dozen other companies before them.

This is the issue with low production vehicles, and when you come to it, sometimes its just more fun-for-the-buck (or time) to use a car where they stamped them out in the millions instead of what amounts to a bespoke product.
People like Mike Jones, etc who are specifically in business to produce custom cam designs rely on the fact that you can easily get cam blanks to grind whatever they tell you....
It is suprising, but not shocking that this interested and motivated OP can't even get the time of day from cam producers.
And you would need 100 of them run to make it feasible.
And how much is a cam for a CTS-V?

And to answer your question I do not know the exact process that they use. You could call and ask.

This is the companies listing of MB cams that they have reworked. I have not been able to get a response from them though. The complete list of other manufacturer cams they do is impressive.

Elgin is a premier cam grinder and rewelder. Dema, the owner, may not be well right now, and I am Not sure who else may be able to contact you back. You will Need real cam Specs to give them from my experience.
