Question for the all mighty cam gods! - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have a cam out of my 327 that was rebuilt 5-6 years ago. I don't have any idea what kind it is, or the profile. It was a good idling cam, and had quite a bit of low end torque. The numbers on the end are: C1H270S or C1H27OS. Is there anyone who can look up these numbers and tell me more about it. It also has CWC cast into it, does that mean anything to you guys?

Thanks

Jason

By just lookin at the number i would think its a comp cams magnum series 270H which has a 270 degree advertised duration and 224 duration @.050. thats just a guess though.
