1979 CLEAN F250 TRUCK mileage question
I have been given a 1979 F250 Ford, 2 wheel drive, camper special, with perfect paint and upholstery, 460 engine, garaged and up on blocks for at least 11 years.
The records which are quite complete show the fuel mileage at around 8 mpg in 1994 and early 1995.
It runs very well but is not road worthy as the brakes are none existent and will need to be rebuilt. All of the seals will probably need to be replaced as well. After running for an hour or so, the compression is 185 + or – 2 lbs on all cylinders. There is no sludge buildup inside of the valve covers.
The transmission shifts well with no strange noises
The truck is totally stock.
It was owned by a meticulous school teacher who used it for a time and drove it on camp trips. The total mileage is 74,000.
1. What can be done to improve the mileage.
2. What problems can I expect from the automatic transmission.
3. Is it worth converting to a manual 4 or 5 speed transmission.
4. What about the gear splitters that install between the bell housing and the regular 4 speed. I have access to several New Process 4 speeds as well as bell housings, clutch parts, etc to put all this together. Is it worth doing?
5. If I need to change seals in the transmission and engine why not change the transmission to a manual.
6. I have access to several Dodge NV 4500 5 speeds. Would they be of help for mileage?
