I have thought about doing this on my fj40. I own the holley 500cfm 2brrl carb almost new already. Right now I am running one of those cheep chineesium carbs. @projectTuRD you should look into that. honestly I have not had any issues with my knock off carb. However I did see you are having issues the the fitment. I wonder if the air horn is interchangeable
I would run an Amazon special if it came with all the various brackets for the throttle cable changeover. I also have a ‘tall’ spacer if that matters. I’d like to keep as much of my air cleaner stuff as I can and run just a different top or whatever.
Is your distributor vacuum advance or vac retard? My 11/69 was a vac retard version so I eventually updated to a City Racer Fuji carb (basically a copy of the same carb a trollhole carb is) and a DUI distributor. The trollhole carb ran fine, wasn't my issue. Robbed it for a few brackets for the Fuji. You could do a later model Toyota vac advance dizzy.
