You'll save about 150 lbs over just about any SBC, nearly the weight of an entire passenger. You'd have to swap over the EFI system but that just opens up all the EFI tuning options to you, and in that regard I just have to echo what everyone else has said: you're better off injected if you want the best possible economy.

My Canyon has the 2.8L previous version of that engine. It has plenty of power and torque. I keep up with traffic shifting at 2500 RPM, 3000 if I'm pulling out onto a highway. I've wondered what mileage I could get if I had that engine in a smaller truck such as an S10, especially if I added the six speed manual transmission from the new Chevy Colorado connected to a 3.42 rear end.
Please do this, I want to see the results.
