I assume you have a 427 side oiler block and perhaps you're not getting
oil to the rocker arms and believe the cam bearings have spun....if this is the symptom perhaps regular FE cam bearings were installed and not side oiler bearings with the additional holes to feed the cam bearings.....if the engine has not been operated too long you may be OK...if it has then things have to corrected and you may have damaged components...Again, perhaps I'm ahead of the symptoms but usually when someone complains about problems with the side oiler oiling to the rockers it points rigth to this error in assembly. FE's also have cam bores that can make installing cam bearings that will end up with the correct clearance to the camshaft a problem too.....many times these bearings will have to be lightly TLC's to have the cam turn easily......
.....let us know the symptoms and what's going on!
