I agree with 55dude. The engineer in me always is looking for the most elegant solutions. I prefer to use tested GM parts, when possible. Many later model Chevy sixes had ps and ac. GM was very good about designing parts to fit a variety of platforms over lots of years. I have not looked at the six ps but bet you can find a setup off of a 60's 235, 250 or 292 that will work or is easily adapted. The HAMB guys are very good at it. A lot of the after market stuff was designed after something a guy in a garage figured out.
