'57 ford fairlane

[old1957]

I bought a 1957 Ford Fairlane 500 with a rebuilt 312 engine, manual three-speed with overdrive....85,000 mi The engine was totally rebuilt in 2000. I have the original rebuilders (permanently closed) parts list. I would like to find out what the cam replacement (p/n 312-8888) really is. this is the p/n written on my parts repair receipt. I cannot find this part number any where. My receipt also says "mild cam, 9.7 x 1 comp....bored out .040. Can anyone tell me what cam I may have in this engine ?
