Transmission and tire questions
I recently completed my maiden voyage and shakedown cruise on my '69 Chevy skoolie with an '80 350 V8. Aside from a couple of small problems (ie flat tire and bad coil) which popped up, it was quite fun!
Of course now that things are shaken down, i have a couple of questions...
First: I've got a 5 speed manual, and the syncros are going. I can double-clutch no problem, but sooner or later, i'll need to either rebuild or replace. If I replace, is it possible to get a tranny (used of course) with a better gear ratio? If this is possible what would be a good ratio to increase highway speeds? Don't know what mine is, but i'm not getting real good highway speeds, about 55mph. Could go faster, but the RPMs are pretty high already.
And second: My tires. I've read the chock-full-of-info Wheel FAQ, but i just gotta get this clear. I've got 9R20s (tube tires) on split rims. Tires need to be replaced. Can I upgrade to tubeless tires on the same rims? If so would i be looking for a 10.5R22.5?
