hello again everyone
I hope all our florida 'bolters are keeping out of the way of the hurricane. Crossing my fingers for you.
I was going through my boxes of old removed parts I got from the PO of my 53 1/2 ton. I saw in one box two pieces that look suspiciously like the ring/pinion pieces that several online retailers sell to give the old trucks better speed.
When I was driving it back from purchasing it, I noticed it seemed to be really good at 50 ish miles an hour, no struggling or high reving and the tach stayed usually at or below 2000 rpms. I kept thinking "this old girl wants to go faster". But of course I didn't give in to the impulse

But I am thinking that the gearing might have been replaced.
I was wondering if there is an easy way to tell what gear ratio is on the truck? I am btw completely ignorant, but working on becoming only slightly so.
Also, some of these old parts look like they're in good shape---I have no idea what most of em are, but is there an advantage to keeping it all? Or should I try and start giving them away? like an big old heater thingie (PO put in vintage heat/air) and what looks like a couple of fuel pumps, buncha brackets etc.
I can call the PO if I can dig up the old number, but thought it would be interesting to learn, also.
