Re: !!! Mpg !!!
10-12 is pretty common.I`d lose that Holley 600,though.That`s gotta be the worst carb they ever made.You`d be better off with a 650 or one of thier Avenger series.O/D only helps at hiway speeds.It`s all about engine speed.With O/D you can go faster and use the same amount of fuel or drive slower and use less(in high gear).Without it,I just don`t drive over 65.I`d say keep the 3.08s.They are like having O/D.As long as you have the torque to get you rolling they work fine and love rolling you down the hiway.A manual would help alot.I get 12.5 in my`72 K2500 350/TH350/33s.I got the same in my`72 K/20 400/4spd/35s.
