Low buck 360 build
Last engine I built for my 318 , the new cam bearings were fitted but I could not get the camshaft in. After much looking I decided it was the second from the back that was tight. I tried to use a brake hone but that failed so after a while I found a piece of pipe the required size, happened to be my alloy floor racing jack handle and taped some wet and dry sandpaper around it and just put that into the bearing and kept turning it while lubing with WD40 until the camshaft fitted without binding. It worked for me!
