[SCOTI]

The ID numbers are usually stamped on the front or rear 'face' of the cam. The timing gear can be removed from the front & theres a galley plug on the rear that can be removed & replaced (basically a freeze plug for the cam galley).

That being said..... Even w/the numbers, you may/may-not be able to positively ID the cam. I did this on a gifted 406 a while back. The numbers were on the rear of the cam but matched nothing I found on the internet. I spoke to a guy that had his motor built from the gentleman I got the 406 from & he told me what the cam was because they discussed it when determining what to use on his motor. When I looked up that 'current' specific grind, the numbers don't match.
