I am looking for an engine recommendation. I have a 1970 FJ 40 that has a sbc in it and I am also struggling with the carburetor stalling on steep inclines, possibly also due to altitude. Adding fuel injection is about the cost of a new engine. The sbc doesn’t feel right to me and I would rather not spend that sort of money on it. Would a 3fe be an option that would mate to a 4 speed transmission? Are the diesel options 2H, 12ht, 3bt affected by altitude or angles? Any other Toyota engine to consider? Thanks for the input.
