I am looking for a 240 or 300 ford 6 to install in a 70 F250 to try to get better gas mileage and the 360 and C-6 that are in it now are very tired,I have a couple of AOD trans that I would like to install behind the six to see if I can get 20 mpg out of this truck as it might have to make a few trips to work as I drive 45 miles each way. If there is anyone with ina reasonable distance from dayton ohio that has a rusty 67 to 79 ford p/u with a good six I am intersted in it.
