Another newbie question. Ready to install new cam bearings, 1936 221ci. Does the big oil hole or small oil hole in the bearing , mate with the hole in the block?
Rear bearing only has 1 hole. Thanks in advance.
 
I always mate the large hole to the hole in the block. It allows for a slight error incase the bearing isn't turned just right .
 
Just check so the pushrod for the fuelpump doesn´t hit the bearing.
On the regular sets i have you have 2 identical long bearings and a short one...not a different one for the rear position.
 
I always put the big hole at the top - and as noted, make dang sure the fuel pump push rod goes through the rear one!

My reasoning is that the majority of the pressure from the valve springs is pushing the cam DOWN - so I like as much bearing surface on the bottom as possible. Probably makes no real difference in that the oil pressure should "float" the cam, but I think this way anyway! LOL
