I have a 1979 f150. I recently had the engine taken apart and basically everything replaced. I drove the truck for roughly 3 weeks and I noticed that when I turn the ignition off, the truck spatters and tries to keep itself idling. I ignored the problem by just stalling it out to turn it off. Now all of a sudden my battery keeps draining. I can jump start the truck and drive it for a day or two, but the battery slowly drains and has to be jumped again. The alternator was just replaced and has good power to it. Any answers for either problems would be appreciated.

Battery could be a whole host of issues, but I'd start by replacing the battery since you didn't say when that was last done.

Sputtering is called "dieseling" or "engine run-on" and typically means that its time to rebuild your carb although it can be caused by things other than the carb. Carb rebuilds are cheap and easy, I'd recommend it highly and it will eliminate a few possibilities that could be causing the run-on.

Drive it to your local parts store and have them check your charging system, for 'free'.

All good replies for having the charging system checked.
It sounds to me as though there is a constant electrical draw.
I would look to the ignition switch and it's connections. Ford did have some issues with an actuator "pawl" (made of pot metal or white metal) breaking off inside when they moved the ignition to the column. This can sometimes leave the ignition in a "state of start" when the ignition is "seemingly" turned off. Check the connections first because of the engine work, then move on from there.
