Thanks I see this topic is not a new one ,just new to me thanks again

My thought process says the crossdrilled camshaft is the better of the two designs used for the Y.  This is supported by the fact that Ford went back to the crossdrilled camshaft design for the 1963 & 1964 292 engines.  Ford recognized the topend oiling problem early on and the FE was designed with the grooves cast in the cam holes of the block which fixed those topend oiling problems seen on the Y engines.  If I had my druthers, the Y-Block's center journal on the camshaft would have no holes or grooves and the oiling to the topend would be supplied either by a groove on the O.D. of the bearing or a groove machined into the center cam hole of the block.  I have welded up the groove of the center journal of a camshaft here and reground it so it’s smooth and that one is in a running engine now.  Only when I have the opportunity to see that engine torn down again will I get a better feel for how much improvement this is over the original designs.
 
In the meantime, here are links to past threads regarding oil modifications for the Y family of engines.

I am about to start a rebuild on my 1955 Crown Victoria , just as everyone here I want to use the best parts I can afford. My question is what is the best cam set up for the best oiling. Is it the cross drilled cam or the slotted cam or the slotted bearing I know there are many opinions I would like to hear pros and cons . Thanks again for any help.
