I just did this 261 update/conversion. I used my short shaft 216 water pump with a wide group pulley.

I used the relocator adapter plate for the pump. I already had the wide groove generator. Then I needed to come up with a wide groove harmonic balancer pulley. The fan has the proper clearance to the harmonic balancer and the proper spacing to the radiator. If changing harmonic balancer, If needed don’t forget to drill the appropriate holes in the gear cover for the front motor mount. I also drilled and tapped the crank.

Here are a few pictures that shows my set up.
