Re: mileage motors
My 305 has 189,000 miles on it.
It came from a '77 Monte Carlo. It was repeatedly overheated on a trip from OK to Calif. & back. Has only a 2bbl carb Sat for a year before being put in the truck. Best milage (after tuning it up a few weeks ago) was 18.6 mpg for 1 tank. Before it was 15.mpg. In the Monte, best was on a trip from OK to NM was 21mpg. I am running 3.73 rear gears, stay about 60 on the highway. Future plans: 4bbl Q-Jet or Edelbrock, 3.08 gears.
