Grant and Bob,
Geeze - you guys really look at things don't you!
The engine in the CMP frame rails is a 1962 Canadian Pontiac 261 with the 235 heads. It was easy to drill and tap the required 2 holes in the front of the block ( well, easy for me - the machinist who took the engine apart had it on the radial arm drill anyway ). There is lots of meat at that location, and nowhere near a water jacket.
The adaptor that you see advertised on the eBay to 'convert' an old Chevy six-in-a-row to a modern one is a great place to start, but they don't do what needs to be done to put the 216 parts on the front of the 261.
The relationships between 261 crank pulley and 216 water pump pulley are all very good to speak of at great length over a few beers. I like beer, but I like leaving things alone lots more. The crank pulley, waterpump, and generator drive pulley are all yanked off the front of the 216 and pushed onto the front of the 261. As was the valve cover. ( The 'kit' is the longer rocker stud that a 216 wears compared to a later 235 or 261 put where it looks like they should go.)
The 216 had the same puny oil feed and return lines - and I will put modern filters in the same place on the frame. This will make oil changes easier and allow some degree of cooling to be had. My truck is a very early version and did not have the oil canister clamped to the intake manifold.
Back to the water pump. My early 216 wore a pump with 1 large hole, not the 2 smaller holes the 216/235 models came with. This was a big factor when I was putting back the right hand drive throttle gear - that uses the water pump as a base. This was a real head scratcher early on - as the 216 in my truck was obviously a pre-'military' conversion.
I took yesterday off work to bail my Rochester B out of the carb place in Toronto, so some more progress is on the horizon. That and lots more sanding on the GS box to get ready for more paint.
