Question about 1981 Ford F 100
My husband bought a 1973 ford f100 4X4. It has a 390 in it. He wants me to find out if you can put an inline 6 in without to much trouble. What exactly has to be changed out if you drop in an inline 6. Is it to difficult?
No not much trouble. However it depends on what Transmission you are using. If A stick, then you will need to change bell housing and you will need to use flywheel fro either a 302 V-8 or another strait 6. 300 or 240 which ever you are using will also need the hard mounts from another truck. The mounts are diferent from one with a 6 to one with a V8. Also the radiator if I remimber correctly is diferent in the way the hoses hook up. There will be a little more money to do this change. But it is easy once you make the plan and see what needs to be done. I have gone from a 300 6 to a 302 V8 in a 78 F-150. It was quite easy and i did it in a day. Any more questions ask.
