What kind of bearings do I need for a camshaft?
When installing cam bearings, always work your way from the rear of the block forward. When fitting aluminum cam bearings, it’s important to allow sufficient bearing-to-camshaft clearance, since the harder aluminum alloy bearings won’t wear in as rapidly as babbitt bearings to make their own clearance.
How are cam bearings installed into a block?
Installation of cam bearings into the block must be done carefully to avoid shaving material from the outside diameter of the bearings. This can easily cause a buildup of excess material between the bearing and the block’s bearing bore, which will “squeeze” the bearing, resulting in oil clearance reduction at the bearing inside diameter.
When do you start the cam bearing selection process?
The installation process begins after you’ve accomplished any machining that might be needed (cylinder boring and/or honing, align-honing, deck resurfacing, cam bore alignment, etc.). Before starting, make certain that the block is totally clean.
Do you put lubricant on cam bearings before they are pressed in?
McBroom also advises that on some blocks such as cast iron blocks, it helps to put a film of lubricant on the bearing before cam bearings are pressed in. “Sometimes the bearing can gall and produce an asperity on the inside of the bearing because it is put together dry,” he says. “Surface finish on the cam journals can also be an issue.

Which is better aluminum or Babbitt cam bearings?
The trade-off lies in the fact that aluminum alloy is harder than babbitt but is less forgiving with regard to contamination, cam bearing bore misalignment, and less-than-ideal lubrication. The benefits of aluminum cam bearings, however, far outweigh the compromises.
Where can I get new cam bearings for my Ford flathead?
New Dura-Bond cam bearings are available from Melling. To be on the safe side, check the bearing surface before installation, especially if you bought them via the Internet. Somebody might have abandoned a rebuild and returned the bearing in less-than-perfect condition.
