Guys,

I have a 1988 Nissan Patrol (4x4) that I'm in the process of putting an injected 351 Windsor out of a 1991 f350 ex-ambulance and have a few questions/issues about the pulley/belt system on it

It's a serpentine belt set up (one very very large fan belt)

The ambulance motor had 2 alternators, power steer, aircon, as well as a few idler pulleys on it

Out of all that, the pulleys I need are: crankshaft, water pump, alternator, power steer and aircon

Is it worthwhile keeping the serpentine belt setup? Or should I convert to a twin belt setup (separate belt(s) for aircon/power steer), with the possibility of a gilmer drive at a later stage

As I'm missing the aircon/power steer pumps at the moment (and the bracket that bolts to the left hand side head), would I be better off getting them from an older f-series engine?

or should I try to get it all from the f350 (or EB v8), and keep the serpentine belt?

thanks in advance!

keep the belt if it all fits up in the patrol engine bay

Definitely keep the serpentine drive.
Get the pwr steer/Air cond bracket from an F-series wrecker.
EB-up Falcons use a different setup which has different water pump/timing cover than yours. The EB-up setup is also less compact than the F-series stuff which is a little closer to the centre line of the engine...possibly an advantage in your case?
If you switch to a gilmer or V-belt setup you'll need to change both your water pump and timing cover back to the early V-belt type which is not reverse rotation. So it's big expense for an inferior setup.

Pete.
