Toss the belt driven fan and put an electric on it. They are cheap at junkyards so the only thing you would have to buy is a temperature sensor to turn it on when needed. That gave me 3mpg in my 4.3L vortec.
A TBI spacer is good for a bit of bottom end power so that gives you better mileage since you don't have to give it as much gas to get going. Also look up the 'ultimate TBI' porting mods for a bit more responsiveness from the engine which will also get you a bit of mileage. The OBD1 computers most of the time get better mileage with a cold air intake so maybe if you can make one cheap enough it would be worth trying.
When looking for tires it is normally hard to find actual rolling resistance numbers so if you can't find them look up the tire specs. 51psi tires are best, 44psi is good, 36psi sucks. Also the lighter the tire the better.
