AC compressor on a 248 - best to run it off the crank or water pump pulley?
I'm figuring out a Vintage Air system for my '41 Buick with a '49 248. What are the bearings like in that water pump? Do you see a problem with running a dual sheave water pump pulley and running the compressor off the pump? Or, alternatively, is it possible to separate the harmonic balancer from the crank pulley and make a dual sheave crank pulley? Running a dual sheave water pump pulley might be easier, but it seems like that might cause premature failure of the water pump.
Thanks for any input.
