The Melling M-45 is virtually a bolt-in swap. It's the same one that fits the 235 engine, and only requires a bit of creative plumbing to connect the inlet and outlet tubing. I'm working on an adapter to fit a small block V8 oil pump (Melling M-55) to stovebolt inlines, including the 216, which will supply about 30% more volume than the M-45.
