I do it the other way- - - -I use my lathe and tool post grinder to reduce the diameter of the big journal cams to fit the 216 block. I've fitted a couple of 235 cams to 216 and early 235 blocks that way, and it's a fairly simple process. I use a carbide cutter bit to rough out the journal a few thousandths oversize, and then surface finish the journals with the grinder, and do a final polish with emery cloth. I'll be using the Melling CCS-1 cam in my prototype. If dyno tests look promising, I might commission a custom grind cam for a later engine. I'm looking for good low end and midrange torque, as attempting to get high RPM performance from a stovebolt with its stone age port design is a fool's mission. The Ford 300 or the International/Jeep 4.0 Liter head would be a much better candidate to use as a starting point to make a hotrod inline six.
