I have a set of 91 cams that i got from Mastaflash today. They both have the "53f" mark. However, the cams are marked with another number in the middle of the cam. One has a big "2" and the other has a big "5".

Can anyone tell me anything about these markings? And which is the intake/exhaust?

Thanks for your input. I may have to ask NISTECH on this one.

Just casting numbers, could be cross referenced to determine possible shim sizes if I remember correctly.

Never did figure this one out. I can feel the difference in cams by just handling the lobes. One seems larger than the other, denoting more lift.

I would love to see some more information on this if possible. Anybody got some info?
