Re: 4.3l vs. 5.7l in a commuter truck
"OR" if you want REALLY good mpg and NO SMOG EVER! get a 6.2 for your truck. In my '82 1t I got 19/21 mpg and it had 4.56's! No more spark plugs,cap,rotor,plug wires,etc....no more smog! will run on almost anything. The only thing you'd have to wire in would be a glow plug controller.,uses small chevy mounts and pretty much drops in.
