It was done along with machining the connecting rods for insert bearings to provide full pressure lubrication to the rods and eliminating the dippers, troughs, and spray-oiling system. The spray holes in the rod caps are plugged and the dippers are removed. Fitting the Melling M-45 oil pump for the 235 and reworking the oil pickup plumbing a little would also be a good idea to increase oil volume. I'm working on the details of putting an increased-stroke 235 crankshaft in a 216 block, along with several other modifications to create a 266 cubic inch inline six with full pressure oiling that looks exactly like a 216 from the outside.
