Unhappy Help...!!!

At 800 miles my newly built 460 had #7 exhaust lobe wiped off the the cam and the engine builder/machine shop suggested it was poor brake-in procedure but agreed to pay 1/3, with the mechanic paying 1/3 and me 1/3.

The new cam ran for 20 minutes and four lobes were ground off of it!

Now the machine shop is saying this is because of modern oil with no zinc/ moly and that for the last two years it has been happening a lot.

What should I believe here?


The specs are here ... http://www.tricityevents.com/CobraEngineSpecs.html

Thanks, Greg.
