What options exist for removing the vacuum pump and going straight to the PS pump?
Ok, so I think I've been able to answer my own question. It doesn't look like anything is off the shelf, but I did find an article on 4btswaps where someone had one custom made PSC Motorsports. The solution looks simple and elegant. I'm talking with Randy now to determine the necessity.

UPDATE: it now looks as if the pump above is modified from a 4BT engine, not a 6BT. It's not that it has been modified, but rather that the pump itself was upgraded/replaced on the 4BT assembly.



In looking at some of the other conversions, I haven't seen you guys have to contend with this, or maybe I've missed something?
