Re: What's your MPG?
With 3.05 gears and 33's I'm not surprised you have the pedal buried.

Re: What's your MPG?
65 with a SB 350 paired with an SM420 4 speed.
I'm not sure about miles per gallon...but I do stop for fuel an awful lot for some reason.

Re: What's your MPG?
I know once upon a time my SWB 402/400TH got 10 MPG. Since then it's been punched out with HP 396 heads. Without caring to check probably 8-9 MPG. Pretty bad, but we don't drive original engines for the MPG
