I took the saginaw pump from a 1975 318 to put on my 440. I bought power steering brackets from 440 source. I mocked up the front of the engine, and my ps pulley is way out of alignment with the crank pulley. It sits about 3/4" further back than the crank pulley.

My first thought was to take the pulley off and shim it, but after I got the first nut of the shaft, I could not get the pulley off, it must be a press fit.

What are my options? Is there a puller tool I can use to pull the pulley off, then place a shim behind it, then reinstall?

Or do the small block pumps have different pulleys than the big block pumps? If thats the case would it be easier to just buy a new pump/pulley for a big block?
