It is sucky mileage but mine isn't much better and I don't know why. However I've always felt the 360/5.9 was a mileage *****. Even the old "LA" 360s I owned were not good on gas. I often wonder if its the basic "oversquare" bore and stroke combined with the cam retarding for emissions purposes.

i get 13 city, and lets just say great milage on highway. i have a 26 gallon tank, went to Maine, 283 miles and it took a little less than half a tank. but it was all highway, and maybe 8 miles city.
you just need to put the right parts in them. im getting that gas milage, and havent changed my plugs yet lol. cant get the heat sheilds off, and the Dist.cap had corrosion in it when i changed it so i can only imagine what the plugs are like. Got a new ported and polished kegger mod intake with hughes plenum, MSD 8.5 mm wires. Accel coil, and im getting that milage.
cant wait to see what its gunna run like when i change the plugs (attempting again tonight lol)
All in all i love the 5.9L. and im only just getting started with her...
