An engine for a 71 F-100 or Econoline that is 8 or even 10 years old NIB will have the hardened valve guides. Ford fixed that back in 1980. You also have a flat tappets and I believe you are correct about not being able to covert it because of the lack of cutouts in the galleys. That should be a 210 HP engine with a 2 barrel carb at 9.5:1 compression.

A cam that gives more low end torque, headers, and 4 barrel would wake that 302 up. The early 302/5.0 had a different firing order than the later 5.0's. The later 5.0-HO's had the same firing order as the 351 Windsor. So if you want to put a 5.0-HO fuel injection system on it you will need to find a flat tappet cam with the 351W firing order to match the fuel injection timing. There is a pile of "gotchas" trying to modernize one of the early 302's. Almost all of them are sensor or computer related.
