I have an 82 chevy truck with a 250 inline 6 and was wandering what would be good to do to give it more fuel mileage. I am going to add an electric fan and I was thinking of upgrading the ignition system with performance coil and wires. I think the coils are the same for the v8 engines, but would like to be sure and you can buy custom wires if necessary. I want to get more power and torque, (mainly torque) but I don't want to move the power band up in the rpm range too much if I don't have to and I have seen the split headers for dual exhaust and my truck already has a split manifold with duals, so I thought that might be good for mileage and power, but am afraid that it might move the torque up the rpm range.
