My 51 p/u has a 235, 3-speed and open driveshaft.
I had the engine rebuilt and have driven it from Florida to Virginia where I now live and I drive it to work in Arkansas. This I have done 3 times,
1500 miles round trip with no problems. Question is the gas mileage? I only get about 11 mpg at around 62 mph. What can I do to improve the gas mileage? Thanks in advance. Pilot | | |

There is enough good in the worst of us and enough bad in the best of us that it does not behoove any of us to criticize the rest of us.

You won't need to do any work to the driveline. Here is a site that will show you exactly what you are going to be looking for at your next swap meet. (I found one at a garage sale for $20 and am putting it in my wifes 55 1st. Borg Warner Overdrive
