Another option is the Edelbrock (Carter). The way the secondaries work give
a bit of latitude with a larger carburetor. I picked up an Edelbrock
(cheap - of course) that is a 625 CFM. My 289 has an unknown, but more
radical cam than stock. Ideally I wanted a smaller carb. However, when I
looked up the primary side it was the same as a 500 CFM. So, when (if) I
ever get my car going I was going to slow the opening of the secondaries and
hope for the best.
Theo, isn't a Canadian gallon different from a US gallon? There is a guy on
my Mopar side of life who claims 28 MPG from his Chrysler 5th Ave. with Auto
(no overdrive). He lives above the great lakes also.
Duke, 16.8 MPG @ 78 MPH (3,800 rpm) with 3.07's doesn't sound all that bad -
considering.
