I recently picked up a few cams that are from an E34 M5, and would appreciate any help identifying them. Purchased from a seller who bought them from a former Dinan tech many years ago, but that's all I have to go with. Does anyone either have their engine apart to share the numbers on the cams with me or have a suggestion to match confirm that they are what they are before I start with the disassembly?
