difference between F and 2F engines?

[lunap]

I have a 1980 FJ obviously with the 2F. Runs great, easy to maintain, etc.
I have looked at some older FJ's with the F engine - they look a lot simpler in design - besides the obvious part differences how do they run differently, is the 2F more HP?
what about maintenance? Are the 2F's more preferred or is it just personal choice as to what is a better engine?

I know very little but from what I understand the 2f has a bit more hp as well as a superior oiling system.

If you strip a 2F down to the basics it will look just like an F, the 2F has a better oiling system, which the 74F shares, and more cubes+ a tad more HP. As old as they are, they seem to fail oiling wise with no warning and x plode.

im getting ready to tear into my 2F here pretty soon to replace seals bearings etc and was wondering how hard is this engine to work on? i work on dirtbike engines lawnmowers and i even rebuilt a mopar slant 6 and they all worked fine after i fixed them so with the experince i have a 2F isnt the hardest is it? cause i was looking at the microfiches online and they ***look*** pretty straight forward.Is this true?

If you did a slant 6 you can do a 2F, just make sure if you have any machine work done, the guys are aware it is metric and they are old skool....You want at least one greybeard there.
