The 350 TBI pickup actually gets better mileage in those conditions than the six banger jeep, though it does a bit better on the highway, 20-22 mpg.

I'm not sure what all was wrong with mine. Possible plugged cat, possible wiped cam lobes, possibly low pump voltage, and goodness knows what else. If it was in proper trim, it would have done better. But I figured if I was going to put the effort into an engine, it might as well be a good one.
I'm sure the TBI is better than a carburetor. However I see it as just an intermediary step to a LS. If I'm going to mess around with a computer controlled engine anyway, it might as well be an LS.
This thread got off topic.
