[VB] Transmission Rebuild

[SAM WILLIAMS]

I have a 63 single cab, with a 1600 DP meximotor and a 3.88 R&P. I have type 3 twin solex carbs and an exhaust header, so my guess is 60 BHP. With my 205x75 15 tyres I get 60 MPH at 3000 RPM
It is making a noise , it was put in in 2006 and I am talking to Rancho. I think I will go with the same tranny and the will give me credit on the R&P if it is in good shape.

Chris,

It’s so funny that you have FI because just as I was writing “what carb are you running” I thought “well, maybe he has FI...”.

Are you running a stock system or something like mega squirt?

Anywho, thanks for the tips: 4.125 seems like it might be the way to go if I’m not sure on the 1600 versus something bigger.

Cheers,
  Tom

Was crazy driving out to Buses By the Bridge with a bunch of other buses. I had a half tank of fuel in my 15g tank when everyone else was empty on their 10g tanks.

I’d kinda like to go with the 3.875, or at least a 4.125 (I think 4.375 is stock in the 67, but it was 4.125 earlier in the 60s?) if I could get away with it.  Cruising below 3500 at 65 is desirable, I just need to still be able to tackle the hills out here.

>>> If your motor is larger than 1600 I would go with the .82 4th gear. That is an 8% increase in gear ratio over the .89. resulting in freeway rpms being 8% lower.  Less scream from the motor. At 65mph you should see about 3600rpm if you have stock sized tires.
>>> I have a rancho rebuild with a 3.875 R&P and the .82 4th. I see about 3350 rpm at 65mph. My motor is a 1776 in my splitty. I have power enough to go easily 70 on the hwy. Don't like to go faster.
