Engine swap
I have a f100 that had a FE. It needs a new engine and I have a guy with both a FE but also an Inline 300. Depending on the condition of the FE I might want to put the 300 in instead. I was wondering what all would have to change to accommodate the 300

Bell housing, exhaust, possibly cooling, mounts--l think it's the same perches but they have to be moved. Carb linkage and possibly fuel lines in engine compartment.
All FE motors are not created equal. Check those engines carefully.

manuel. I’m also considering a 361 FT. It only has 18000 miles on it and runs good. I don’t know what I would have to do to it though

The easiest is to go with the FE. The 300 is a great engine, but the amount of parts needed for the swap is a lot unless you can find a donor truck. Just my two cents. Good luck either way you go. Also stay away from the FT as it is totally different!

I think I have to go with the FT. From what I can find, I’ll have everything I need on the parts truck and it will be cheaper that way

You should look at this very carefully. The FT engine shares a few common parts, but they are few. The FT has a different style crank with very different sizes. You will need the trans, bell housing, mounts, exhaust manifolds. You will need to retain the FT dizzy as well which is a not great. I still think going with the FE is your best bet!
