Please id this cam

The lifter split is 67 and earlier/68 and later.
The difference being the pushrod seat diameter.
67-earlier BB pushrods had the bottom end reduced to 1/4”, and the lifter had a recess that size to fit.
They are also slightly longer than the 68-later pieces.

The 68-later pushrods are 5/16” on both ends.
The 68-later lifters have a pushrod seat to match.

However, none of that changes anything on the cam.
You would just use the matching pushrods/lifters together on the cam.
That being said, I’ve never seen any listing for MP cam/lifter kits that came with other than the 68-up style lifters.
