FS: 951 Aftermarket street camshaft
Cam that I bought from John Manelis (vette951s) a few years ago when I bought a 968 shell from him. Was apparently made by a manufacture that made Milledges cams in the early 90's. Maybe Web Cam or Megacycle Cams? Stamped '3073' and 3-91 (date I'm assuming). Mileage unkown. Cam lobes look great, some wear on the bearing lobes.
Specs:
In/Ex centerline = 108.5°
Max. lift = .462
Intake duration = 236.77° @ .040" / 46.80 BBDC, 9.92 ATDC
Exhaust Duration = 236.72° @.040" / 10.16 BTDC, 47.18 ABDC
In/Ex duration @.006" lift = 272.2°
Small chip out of the nose of the cam at the keyway, but the cam is fine to run. See pic.
Some journal discoloration, but nothing you can feel with your finger or nail, all feels smooth.

Anyone have a real world account of what gains a cam like this (or similar) gets you on a street car? Not so much power, but drivability/spool/etc. I'm a fan of the cam in my NA and am interested in something like this for my 951 now as well.

I'm using a Vitesse Camshaft on my 951, and I love it.
I have no experience with a k26/6 turbo, but with a K27/8 it seemed to spool a bit earlier than usual and the top end was great ( I dont really pass 6000 rpm )
Porsche and Bmw sacrifice exhaust valve timing instead of using an EGR valve to lower their NoX emissions ( and since its a SOHC nothing can be done to change the exhaust valve timing without affecting the intake valve timing)... so aftermarket cams really wake these cars up.
