Bob -

#64 jets are specified for the center carb on a 427/435hp car.

Unless you in a high altitude, 66's run better.

Robert - Are you noticing some 'surging' when you're driving, plugs a bit too white?

Re: 3x2 jetting

Make sure you are working on the right circuit. If the surge is at 2500 +- the carburetor is still on the idle circuit. If the surge is at 300+ RPM then it's the main circuit. The idle feed restriction can be opened just a bit to correct this condition.
