3FE Head and 2F block (2FE) build questions (15 Viewers)

[matt.mcinnes]

Kinda makes one wonder why Toyota cut down the 2F block to shorten the stroke before adding EFI.
That trim widened the power band and made the engine more "driveable"... especially when mated to an auto tranny.
Obviously in the design stages, they put EFI on a 2F and didn't like the outcome. So the 3F was born.
Might be something to consider.

In Australia, 3Fs were carbureted. Toyota saw the 3F block as an improvement over the 2F and the Dyno results proved it.

I can see the logic of swapping in a 3FE head on a FJ60 2F block that is sitting in the truck.
I can't really understand the reasoning behind putting an older design, 2F block back in a FJ62 and bolting on the EFI head when using an auto tranny unless the new block can be acquired for dirt cheap. It seems like going backwards. Toyota wanted nothing to do with EFI on a 2F.

Just sayin...

The 3FE was a result of emissions. In Oz we got a 3F Carbi in manual and 3Fe in auto only. Very rare to find a 3Fe in Oz. It was a dog of an engine killed by emission standards.
Remove the EFR and build a 2Fe then you will understand why.
