G'day again guys, I recently bought a 1983 Blazer to ferry my band equipment around. I only ever intend to use it for this and not offroading. I would like to know if there is anything I can do about fuel economy as last night I calculated my mileage at 7 miles per gallon!!!! The engine is a Small Block, although I have no idea on how to tell the size. The carb is a 4 barrel square bore Holley and again, I have no idea of it's size. Can anyone suggest and good carb setup that will allow me to get miles per gallon into double figures at least? Also, the front shaft has been removed, will this effect the vehicle in any way, other than 4x4ing? I'm an expat living and working in Saudi Arabia and technical help is very thin on the ground out here. Any help will be appreciated, thanks.
