The last time we went to our local U-pull-it, there was a wrecked Navigator with a complete 32 valve 5.4 with I think 14xxxx on it. The owners said they would sell the motor for something like $230, pretty sure that's not including the harness or computer or anything else. If they still have it the next time we go down there, either me or my friend have decided we are coming home with it...if I get it it will be going into my old F-150, he is looking at putting it into a fox. However neither of us know much about the 4 valve motors. Is that a decent price on that engine? Anything to look out for on them? What are some good upgrades such as heads and cams and intake? I've seen some carb'd mod motor setups that looked pretty awesome even though I'm sure they are pretty expensive to build, but it would be sweeeet to see one in an older F-150 in my opinion.
