On my 235, I bought a modified 250 H/B from Buffalo Enterprises in Washington state....it was pricey, needed to be rebalanced but it gives me the option to run all three. The mounts you can buy from Alan Grove and Old air (as well as others) are set up for stock exhaust manifolds and require some modification if you're running Fentons. I've got some pics in my "Webshots" albums of the install....I run the pass. side alternator belt(1) over the waterpump on the inside groove and the a/c compressor directly off the front groove. My Saginaw p/s pump will run off the front groove of the 2 groove A/C compressor when I get around to adding it. Be advised that you'll be hard pressed to buy all the brackets to bolt on without some fabrication.
