changing a small block to a big block

[denny5625]

This has probably been asked a million times but I'm changing over to a big block and could use some help with a few questions. I have a 1971 2wd short box with factory air and needed to know what pulleys, brackets, power steering, alt. etc.... that I need to change over and hopefully where to get them. I already bought some big block motor mounts and ordered some "shorty" headers from Sanderson Exhaust. Thanks for any help.
