ba motor into an f100 how hard is it what would i need to do can anyone help cheers

Which BA motor are you talking about here?
No motor from a BA will just "bolt right in". Completely different bays.
Possible, but how much time and money do you have available to do it?
Remember, it will need engineering to be roadworthy, custom engine mounts, custom tailshaft, not even sure the gearbox lines up right in the tunnel. This can turn into an expensive project VERY quickly.
