AVS2 800 carbs

Looking at the specs the AVS2 650 is more of a spread bore design, even if Edelbrock doesn’t call it that.

The 650 has primaries from the 600 (1-7/16”) and secondaries From the 800 (1-3/4”).

Carter avs carbs are that way. The throttle plates are larger on the secondaries than the primaries.
