There are a group of farmers / mechanics in the southeastern part of the country (bryon georgia i think) who are rebuilding older pickup trucks using from old tractors motors that get 40 mpg. i would think the same thinking could done with the old chevy trucks. the website is:
www.shadetreeconversions.com. now that would be awesome to have and old chevy truck and not have to stop everytime you took it out to get gas.
