Topic: ring and pinion gear
Posted by dextrojw on 10-07-2014 20:57:07

Hello truck forum, I have a 1963 f350 dually that has had the engine and transmission changed, but nothing ever done to the rear end and can only get 45mph @ 2500rpms. The engine is a 1971 - 1974 351w, with a c6 transmission, but it still has the 488 rear end gear that was connected to a 4 speed and the 292cui engine. What I'm hoping for, is to find a 373 or 354 ring and pinion gear to be able to at least do 60mph at 1500rpms. I don't mind changing the entire rear end if I could get a 373 gear. If anyone can help, thank you ahead of time, and I'm hoping to hear from the forum soon. thanks again

Yep those old 1 tons where gears low and slow. I have a 1965 F350 with a 300 and 4 speed and has less then 81K miles on it. My dad blew the rear end out of it and we replaced it with a 4:11 one and can now get up to around 55-60 before it had a 5:73 rear end and 45 was top speed unless you went down a hill and pushed in the clutch pedal

Thanks for the reply. I'll be looking for that 373 or 354 ring and pinion to be able to drive beside you at 55 or 60mph. Have a good one. And let me know if you run into someone with that gear that I need for my 63. Take care.
