On a Scorpio 2.9 it would mean custom re-plumbing of the power steering and A/C since a 4.0 variant never existed for that platform. I suspect that would result in me ditching A/C entirely. For the power steering, I would probably explore the idea of sticking with the factory Saginaw pump, swapping in a Micro-V pulley and somehow adapting the pump to the 4.0 bracket.Why in the world would you want to convert a 4.0 to V-belts? Especially using parts that are harder to find than the 4.0 stuff?
Scorpio is totally different in that regard. It uses a small Saginaw PS pump. It's the same pump as used on many GM applications of the late 80's / early 90's.I am not familiar with the Scorpio setup. The regular 2.9 uses the same PS pump as a 4.0 just with a different pulley.
