'65 LWB
283 V8 :: PS / PB / elect ign
350 auto with towing shift kit :: I think it's a TH?
3:73 rear end :: guessing
Engine and trans rebuilt ~ 3 years / 3,000 miles ago
Last owner used it on the farm sparingly for his horses. I don't tow anything, but I bought the truck to USE it. I haul lumber and furniture and mulch and stuff with it. She ain't a show truck and I have no plans of hot-rodding it.
Problem is I can't drive it on the highway for long at all. It SCREAMS at 70 mph. This is what I need to remedy. (That and I get maybe 8-9 MPG.)
What's my best option?
- Change the rear end? (to what?)
- Go to a 700R4?
- Do both?
Thanks in advance for the input - you guys are the best!

If you do the 700r4 you can leave the 373 rear end. If you do the rear end 308 or 325 will be good.
