We build custom adapters for that carb all the time for the roundtrack cars, since it's the only one the Nashville Fairgrounds track allows. Those are going on smallblock V-8 manifolds, however. It wouldn't be too difficult to make one for a 6-cylinder.

On my set up,the carb sits fuel bowl foward. The Holley on modified intake has great throttle response,more power and yes ,better fuel mileage than the stock carb or those ugly over rated Holley Weber 2 bbl carbs. | | |
