[V8Vairs] Carburation

[GnKHOFFMAN at aol.com]

I have an old aftermarket AFB (Carter?), 600 cfm, on a 327 in my Crown  Car.  
I only rebuilt it (don't think there are tuning kits available for  it).  It 
has a mechanical secondary.  The only time I checked mileage  was for a 220 
mile highway trip, and it got over 17 mpg.  Never checked it  around town.  Here 
in Denver we have to pass an idle emissions test, and I  was told to not try 
and adjust the carb, as it was great on the emissions.
 
I bought an Edlebrock 1406 for my other Crown Car (with a 350 cu in  engine), 
but that car isn't running yet.

Same  experience here. I get about 10 mpg, but it runs great. I've got the
tuning  kit, but haven't installed it yet because I still have to pull  the
drivetrain to replace the transmission.
