machine shop tom Another thought is that the cam bearing bores may be slightly out of line. This can make the cam turn stiff, but isn't really a problem.

BOBCRMAN@aol.com Usually it causes no problems. I try not to use scotchbrite on bearings, I use a bearing knife. If I have a real super fussy customer I will use fine scotchbrite pad to "Hollywood" the bearing. Usually what happens is the bearing driver leaves a very small amount of bearing displaced at the very edge. A knife leaves the removed spot shiny while the rest of the bearing is dull.

BlackRat Thanks. Just curious did you reply to my post at the Club Hot Rod forum suggesting scotch brite on the bearing? If not sorry. If so I did follow your suggestion and it did help although scares the heck out of me to be abrasive material on a bearing surface. As I stated in the post it is still a little tight but the bearing did mic to same spec as the others and does seem to be square in the hole. This might be a really dumb question but since it is turning smoother can this be tolerated and allowed to wear itself in or is it something that I am asking for trouble with?

Thanks
Wade

Cam tight to turn by hand?

Putting my 454 together and everything has been going good until I get the cam installed. I lubed everything with the supplied comp cams lube as well as used a mixture of oil and stp treatment on the bearings and journals. Cam is very hard to get started turning but once I get it started it is smooth. If I stop it is hard to start turning again. Any Ideas why this maybe. A lot of lube possibly causing it to stick?

Thanks
Wade
