I am about to start on my Fj55 build up and before I commit to keeping the 2f powerplant I was wondering if anyone has transplanted a SBC into a 1975 or later rig and what emission hassles you encountered. My Fj55 is a 1979 with a emissions complete 2f I would much rather run a SBC but I know that after 1974 they are more stringent on inspections. My '74 Fj40 with 383 SBC only had to pass the idle test with no visual underhood inspection. I was told 1974 was the cut off year for no underhood inspections. So if anyone is running a SBC in a post 1975 rig can you chime in and tell me exactly what you had to run/do to visually pass emissions. I am in Tucson and we have to get emissioned so just don't tell me you don't need it where you're at 'cuz that's just rubbing it in. Thanks.
