2.8L vs 4.3L
Which is better all the way around, performance, gas mileage, everything between a Chevy 2.8L and 4.3L?

It depends on what you want, and what you are powering
Neither is better all the way around
The 2.8 is better gas mileage, the 4.3 better power

It also depends on how you drive and what you haul.
My wife has a heavy foot
she used to have a merc mystique with a 2.5 V-6 she got 22mpg and I got 29mpg. We now have a bigger merc [sable] with a 3.0 V-6. She gets 25 mpg and I get 26.
I have a straight 6 in a work van, fully loaded it gets 11mpg - better off with a V-8 but empty it gets 19 mpg, I doubt a V-8 would come close.

I had the 2.8 engine in a 1984 4x4 S-10 Blazer, with automatic. It was a dog, and using cruise control, it could not hold 55 mph on moderate hills. I can't comment on gas mileage, as I didn't drive it enough to do the calculations.
I also had a 4.3 engine in a 1991 4x4 S-10 extended cab pickup, with automatic. It had considerably more power, but guzzled gas. I drove this pickup as a commuter vehicle 130 miles round trip daily, and it never got better than 18 MPG. I had friends with full size Chevy pickups with V-8's that got better mileage.
