Camshaft specs needed
I have set of Porsche 911 camshafts, GE 70 314/288. They are a 4 journal 47 mm cam shaft with an MFI drive.
Does anyone have a cam card on these cams. I found the specs, thanks John.

John Daugherty at DRC was able to generate a cam card.
Thanks John. Always the "go to" cam Meister.

They are 47mm 4 journal MFI cams. Now, what are they good for?

No one has any experience with these camshafts?

John would be able to tell you what sort of motor spec these would be used in.
Cheers

If the cams are marked 314/288, that's going to be an Elgin grind. Specs may be different than those showing on the card you posted above. Might want to confirm whether you've got a Dougherty or Elgin grind.

He gave me a general opinion but had no experience with the specific cam. Quote:
I guess you misread the card. The DC cam card generated by John was the actual profile of the cams.

Gotcha. Strange - I thought Elgin was the one who ground the GE profiles for Garretson. Either way, you've got your info now.
