Mike, may be that carter was not fully tuned. Were the throttles fully
opening? Did you try bigger jets for richer mixture at WOT? (that would
not help fuel economy though). Or, may be it was too rich. Did you ever
have black smoke with the Carter? That Holley may start leaking again. If
not, disregard the above! Also, the electric choke may be better overall,
since you can turn it off a lot sooner than the spring will allow you. You
can keep your oil cleaner at the expense of driveability when cold. If you
don't drive short trips, this is no big deal.

Don't think these metal plates are doing you any good. These are not
insulating! Then again, they are not doing much harm either. If you have
space limitations due to hood interference, the insulation may be more
effective if you replace the 3 metal plates with 3 more gaskets!
