Noid,

Does the VN diff head fit in the Bedford housing? Or did you already have a VN housing under your Beddy.

3:55 is gunna be heaps better for towing busy. i would only tow in 3rd gear all the time. otherwise your likely to blow up your overdrive gear. people say even with the v8 t700 only tow in 3rd ay, not a strong enough box.

Mine has a borg wagner in it, I had it widened to suit the Beddy track. When it ran the 186 the ratio was 2.98:1 and worked well with the trimatic but it was to tall for the v6 and th700 with over drive. With the v6 pretty much had to run around in 3RD gear or it would jump in and out of OD all the time.

Busy I don't tow with mine but Ive carried some reasonable loads and it pulled fine. If you have time I would definitely change the ratio before your trip.

Cheers

Ok, to through a spanner in the works, In my Beddie with the V6 / T700 auto, I have the standard diff Duel wheels model, I'ts a 4.1 and the van runs great. around town. open road, and with weight behind it, not sure if I would want to change it, but haven't been on any long trips, so that's another question........... but do have a 3.5 I will  try out .
When I first got the van it reved so high in first gear before it would change, It had a loud noise in the back, thought diff. Ended up with a  reo auto and all sweet, no noise in tne back anymore, no revs on changing geras.

I phoned around today, seems 3.45:1 is a common ratio but they only had one there with noisey bearings - for $150, so will keep looking
