While researching some other carb's today i ran across the following. Carb's 7042118 and 7042838 (large 1.375 venturi's) were installed on all models of that year with the 400 motor.

Document used was the napa carburetor application and parts guide......then checked the nhra eng. Spec. Sheet and found 1.250
venturi listed..maybe typo???/ these carb's have never been machined as the parting line(s) in the venturi are still there....

Any suggestions?????
