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 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.
