hey There all,

I'm a member of corvette forums but this may be a more general chevrolet question. I have a 350 in my 75 vette that I have identified as a 77 truck engine from the vin on the block. It's 350 cid, with a 400 crank. I pulled the cam and can't make any headway in Identifing it can anyone help a guy out? The Cam has "cwc", "cmc", "D5", "C5", "B", "1.5", "1539". These are from the front to the back.

Thanks all
