Background: I just found the guy that bought my dads rolled 1992 FJ80 and I bought it back from him because it was cheap and still all there. I also have 2 FJ60's, one which has been hit and is about to become my project. I am thinking of putting the 3FE EFI and or head also on my 2F block. (I have researched this and know it works but would like some more engine specifics). Questions: Is the 2F head the same as the 3F head? Will the 3FE manifolds bolt on my 2F head? Can I use 2F FJ60 headers on my 3FE head? where is the stroke longer in the 2F? (the crank, connecting rods, or both)? Are the pistons the same in the 2F and 3FE? If I put the 3FE head on the 2F block which valve lifters and connecting rods should I use? Will this change the compression ratio? (raise or lower or same)? Does anyone know the HP___@___RPM and Torque___@___RPM that this combination would produce? What is the red-line for the stock 3FE engine? Other misc. questions: Are the front diff. gears in fj60-62 reverse cut? Does anyone know of any info. or adapters for putting in duel 4-speed transmissions? Do you have to put both transmissions in reverse to go in reverse? Any thoughts on the automatic, good or bad? Any thoughts on the full time transfercase if used with manual hub front axle? I know this is a lot but any help would be great, and short answers are fine. Thank you.
