Gas Mileage Issues

2 things. one easy & quick one not so much.

1. new air filter & fresh plugs. please install them straight and use 30 ft-lbs when tightening
2. switch distributor to electronic. info here: http://www.slantsix.org/articles/leanburn-article/leanburn-article.htm
you will save a ton of money by finding a '73 - '80's car or truck in a junk yard with a slant six and grabbing the ignition parts & pieces there.
