Why bother replacing something that works right and was engineered for that engine? I ran lots of 7448's on round track engines where they were designed to act like a restrictor plate on a Chevy 350 to limit the benefit from expensive cylinder head modifications and level the playing field for low-bucks entry level racers. Those carbs are tunable, but getting one to work right for a specific engine without a lot of tinkering is about as likely as finding a chicken with lips. The bits and pieces in the tuning kit that I still have stashed away somewhere represent around $500.00 worth of parts. You can have your Stromberg professionally rehabbed for a lot less than making the Holley work- - - - -sort of! Stromberg VS Holley is sort of like Ferrari VS Yugo.
