Cam lobe/lifter alignment
Hey everyone ,
want to to get some info on this before I button my motor up. I got the cam and lifters in today. Cam set in nicely. Timing chain abd gear are in. Everything lines up as it should. But I looked in the valley in the center hole where you can see the cam. Looks like the cam lobe and lifter are not centered on each other. Is this normal or is the cam messed up? It’s a new cam and new lifters. Plain flat tappet setup. Cam is a basic RV Melling MT01
Thanks in advance

When you say the timing chain lines up,what do you mean by this? Did this cam come with a spec card telling where to install the intake centerline or did you line line the marks up and call it OK? This is the worst mistake made with cam timing. The cam vendor tells you where they want the cam installed and some disregard this. Not picking on you,just asking questions.

^^^^^^^^^This is exactly my point. Just because the gear marks align doesn't mean anything. A lot of these parts are made overseas and are junk. We had some Cloyes True Roller gear sets marked wrong and they are top of the line parts. Even if the marks are correct and align correctly doesn't mean the cam is in the engine where the grinder wants it. They give you the specs where they want it installed for a reason.

It’s an RV cam. Those grinds are so mild being off a few degrees won’t make any difference. I’ve degreed in a bunch of cams and never found one off even so much as a degree. Of course the one I don’t check might be the one that is screwed up so I check them anyway.
