I’m rebuilding a 56 235 and have some cam questions. It had to be bored .40 over, new cam bearing, crank turned .10, new main bearings and rod bearings, valves, valve guides, seals and springs but I’m not finding the cam I’ve been told it needs. I was told a Melling CCA29 but it’s not made anymore. Just for kicks I checked Oreillys and they show it needs a Melling CCA1 which is of course different specs. I’m seen on this forum to use a cam out of a 261? If the valves are adjustable can I use the CCA1? Also what rear main seal do I need. Some say the fiber wick ones or does it need the neoprene since there’s more pressure. I’m replacing the 216 in my 49 3600. I appreciate any expertise on the subject. I’m sure I’ll have more questions as I go through this build! Thanks
