If you think the 240 or 300 will give better MPG, think again.
The 240 was a slug, the early engines burned oil like a diesel.
Around town, the MPG will be no different than with a 352, 360, or a 390.
On the highway with an I-6, you might ...
might get 1 or 2 MPG extra.
These trucks have the aerodynamics of a brick. When these old rolling piles of misery were new, a gallon of
105 octane premium was around 35 cents a gallon, regular between 20-25 cents a gallon.
Back then, no one gave a hoot about gas mileage.
