Now that you mention it I see that those center holes threads are at a different angle... Any idea where to get those shims/washers? I'd rather not hog out the holes in the intake if I don't have to.
I'm going eventually add A/C so I was trying to plan ahead and get a long nose water pump which means my current pullies will be un-usable.
I was also planning on using the Amsoil "break-in" high zinc oil, How do I prime it with a drill? Again newbie here. Thank you for the reply and help.

These are discontinued but you can make something similar. I think you will have to at least enlarge the holes in the intake to make them work.

You can get A/C on a 67-72 so no need to go long pump for that. I would not use an A6 compressor, but there are kits to put a Sanden on which will have the brackets you need anyway. And if you do go serpentine, get one without an R4 compressor like a Corvette with Nippendenso or the later 4.3 or 5.7 with the silver compressor and then get a Nippendenso to replace it (not an offshore). With any of these you will need a different alternator and I would want a CS144 not a CS130.

To prime the engine you need a priming tool or an old cut off distributor. It's possible to just use a screwdriver with no handle, but I would want the whole thing so it will oil the top end since this engine has been sitting and with all the problems with breaking in flat tappet cams. Some are just shafts that don't close a gap to oil the top end.
