checking cam lobe taper/nitriding lobes

You’re best bet is to send the cam and lifters to 300 Below and get them both cryogenically treated.

Its relatively inexpensive and it’s the single best thing you can do to increase your chances of not having a failure.

Yes, I’ve done it and yes I do it and yes, I’ve pulled stuff apart after it’s run and the cam and lifters look much different when they have been cryo’d.

It’s a couple of weeks turn around including shipping both ways. 300 Below is usually 3-4 days to get them done.

Absolutely worth the money and the extra time.
Can you give us a ball park $$$$?
