Update on 216 to 261 engine switch

[Phil Waterman]

Thanks Guys

Your tips and caution are appreciated. I probably will go with a new oil filter unit need to look for one with the flow rating, will need to relocate the oil filter unit either to the frame or up high on the manifold like the later CMP filter units. I’ll post some more pictures of this engine to my web page I’ve completely disassembled the engine now, to get the old oil that has gone gummy out of all the bearing surfaces and oil passages. Bob the block casting number is 376925 which from info I have means 59-62 the head casting number is 3835913. There is no stamped serial number on the flat behind the distributor, the hidden serial number behind the edge of the side valve cover is 035S.

Given the condition of the valve seats and valves I think I’ll take your advice and have the head done at the machine shop, replace all the valves. Before that though need to mic all the bearings only what to do this once per engine.
