Our FD is starting to make a little noise and assume it will just get louder, so am thinking about a replacement.

Is there a factual Analysis showing the best Engine/FD combination as it relates to MPG? If not, what parameters should be used to make a decision?

We have a 455/307 with Howell EBL/ESC and still do not get 9 MPG,
although it is much improved from the 6.5 to 7 that the Carb. gave us.
We seldom exceed 60 MPH or 2100 RPM. We do not Tow. Very little Hill climbing in Fl, Ga, and Al.

Thank you,
Richard
