I can't drive... 55!
Seriously! 50 is about it. I don't have a tach, but the RPMs sound like they are WAY up there, like the motor wants to blow. I have a 292 with the Ford standard duty three speed (not a toploader) on the tree and 9" rear end with a tag that says it's a 3.70. Any ideas on the gear ratio's for the transmission? Would I be able to change the gearing in the transmission? What would be a good ring and pinion set-up to get my truck to at least go faster than these John Deere and Case tractors going up and down my road? I really do think that I would be who the tractors would be waiting on.

KC I think all the three speeds have a final drive that is 1 to 1. You could jack up the rear wheel and rotate it one revaluation and count the turns on the drive shaft to get a close count on the gears. A 3.70 should get you down the road well over 55. unless you are running tiny tires.LOL

KC a couple of things will effect cruising speed vs RPM. Transmission final drive, differential gearing and tire size. Attached is a calculator to help!
Gear Ratio Calculator Good luck in your quest |
Years back I had a 1960 F100 4x4, 223 six, 3 speed on column, stock axles (about 3.9 : 1). I could drive for hours at 55 with no problems. I could also cruise at 60, but it got loud. (had 7.00 x 15 tires)
If you have not spent much time driving these old trucks, it takes a while to get used to the noise. Spinning an engine at 3000 rpm does get noisy. |
I have to drive 60 mph to get to 55. I felt like a farmer out on the country roads. When I go on the freeway I stay in the right lane and go 60. It's all she's got Captain.
Trying to amass parts for a 5 speed myself here. Thinking T5. Then I can go 70 but then there is that whole no power steering and 4 leaf suspension to mess with. |
