Does the LHS cam have the MFI drive bung? Could be RSR cams. Any photos?

Is the bung detachable? In the picture above, the LHS cam doesn't appear to have any. So, is it a non-MFI cam then?

The race cams have the recess in the end for a bolt in bung for MFI drive or tack drive or anything else u want to drive off the cam. Fine thread, small journal. This is a bolt in bung.

I didn't know that. Thanks.

Are fine thread cam nuts and bungs hard to find?

We just made the bungs, I’ve been using that one for 30 yrs. The nuts aren’t easy to find and also the big spring washer is different. My cams are home made from billets and are hard as the back of Superman’s head. I’ve been running lash cap rockers all this time.
