I think I'm going to slap my 440 into my duster

Also in the middle of my /6 to 440 swap. 71 Scamp has front disk brakes and power steering (Federal Pump) and Air conditioning (Sanden 508s133 condensor). Has anyone kept the p/s and a/c when performing this swap??? Curious what set up will work to fit all these accessories. What brackets and pulleys work? Thanks for any advise
