I am installing a offenhauser intake with a 390cfm Holley on a 250 straight six. Currently I am running drum brakes all around, but am thinking of doing the disc conversion. I am concerned about the Holley interfering with the brake master / booster assembly. Does anybody have pics of this set-up they could share for reference ?? Thanks in advance !!

Oh - forgot to mention. The 390 will be mounted 90 deg. to the motor (linkage to front of motor ).

Thanks for the replys. But my Holley will be 90 deg. to the motor. (Primaries toward valve cover). What I am concerned about is the float bowl interfering with the master / booster. In your posts your carb. is perpendicular to the engine .......
