[William Spence (RIP)]

I am up-engining a 1942 HUP from a 216 to a 261 engine as the 216 is only good for a boat anchor. The 261 is a full force-feed engine & alas I don't have any manuals or info re these engines. It is ready to be put back in the truck but I need info re the oil filter - this engine has one mounted on one of the manifolds but I can't see where the lines enter the block. There is one fitting below the filter at the bottom of the block, but I don't see where the other line goes. Can someone send me a picture of this side of the engine so that I can get this filter set up properly???? Many tks,
