I checked the cam bearings on my 360 to-day and the rearmost one is chipped and clearly damaged. What does it take to replace them/ My manual suggests I 'assume they al right', I think not!
I have done them before , made specosl tools to do it but in my 440 i had ICE do it as thay done all the other work on the block , any good engine builder should be able to do it.
Replacing cam bearings does not require honing, after fitting and ensuring the oil holes are lined up right stick the cam in and check it rotates freely, if not pull it out and check for any slight burrs from the insert tool, polish them up with crocus cloth and re check, job done.
You do need the correct tool to fit them though, it is available, usually as a universal fitment kit.
Been there myself I had a tool made up out of some old altinator pulleys that where machined down to fit each bearing I then pulled them into place using a threaded bar it worked really well didn't even have to pull the motor out of the car
Guys, this might be a dipstick question (i,m still new to this!) but, are the old bearings reamed out to remove them first? They appear to be a machine fit in the block. As the motor is on the floor and i dont have machin facilities is it likely to be easier via a machine shop in the end?
As Alex said make sure you line up the oil hiles correctly otherwise you will stave all you valve gear of oil.
The tool I had made enabled me to pull out the old bearings before I pulled in the new ones
Terry, my mate had a cam bearing replacement job on a Ford small block that left a bill that indicated a little more work than you suggest. Different process on mopars?
