Yep, I really don't really care that much I guess.
Why would you want to ditch the EFI?????

Another difference to be noted is the spacing on a 1F versus 2F manifold for aircleaner placement.
I have a F155 engine. I had changed the valve cover over to a aluminum cover. I was running a Holley but decided to change back over to an Aisan carb. I sourced a 1977 carb and matching aircleaner. The carbs will all swap. I assumed the aircleaner would bolt right up also.
However the spacing of the intake is different. I had to move the aircleaner assembly away from the carb, and drop it down in order for the aircleaner and airhorn to mate up. I made custom brackets for the mounts to the valve cover and simply shimmed the large mount to the head on the distributor side of the engine. I also had to enlarge the depressions on the under side of the cleaner to clear the valve cover nuts.
I assume the 1F's had a similar spacing. But the distance from the block and height of the carb difinetely changed for the 2F's. I also have noticed the visible difference of the air cleaner in a FJ-60, compared to the 77 model and the possiblity that the dimensions of the later 2F's may be different. Does anyone know?
I sold the electronics from my project 62, leaving me a 3fe short block.
Now that I think about it.......
My question should have been will a 2f head bolt on to the 3fe block.
Then any 2f intake would work. The reason for the question is because
I know where there is a 66 fj40 that needs an engine rebuild.
I was considering using the 3fe long block with a 2f intake/ carb in the 66 instead of rebuilding the f in there now.
It is just a matter of putting what I have to use.
Warped the ears on the intake manifold? I would have thought that they would crack.

1/75-1/79: 2F [4.2 liter] 2bbl intake with 5 bolt attachement to exhaust. Port behind carb for brake booster, port under carb for PCV, port in front of carb for filtered vacuum source.
1/79-9/87 2F [4.2 liter] 2bbl aluminum intake with 5 bolt attachment to exhaust. Main distinction from earlier 2F intakes is that EGR ports into the side of the intake underneath the carb, alongside the PCV system.
Old thread, I know but a related question: if you look at the pictures
above of the two intake manifolds, you'll see the four holes for
the carb mount - plus a fifth hole. What is supposed to go into
that fifth hole? Should it be plugged?

Great to see this thread back!
I have a leak between my intake and exhaust on my '78 2F.
I inherited an intake/exhaust off a 60 that I could replace the gaskets on and drop in my '78 40 if:
1) the exhaust is the same
2) My EGR will fit to the later manifold.
Can anyone answer my questions or post pictures showing the two different EGR connections?
Why do you want to swap it out?
Your 1978 exhaust manifold should be the three-piece design, giving you the same advantages/problems as the later model you are looking to install.
I would have the intake and exhaust manifold to cylinder head mating surface trued at a machine shop, and run it.
Your current EGR system is not going to bolt up and work with the later model exhaust manifold.
