318 2bbl Intake Mods ?

Sounds like it was a fun truck !! I am about to start down the road for my "gas mileage & performance" Van project as I prepare for NNN. Sticking to my word on just working with the factory equipment. My job is just to allow the components to preform at their premium. It's going to be a blast for me, as I am so much attracted to this type of project.
Gas sipper, going to be tough with that brick. You should be getting about 14.5 mpg stock before touching anything.
