I would say that I am feeding close to 100 more cubes than the carb is designed for so I think it would work.



i ran a 1405 on a 440/.484 cam challenger w/air+3.91.street car,drove all the time and went on trips too.car ran 13.65's all day,and im a freak about drivability. i jetted/needled+spring kitted the carb,and it was great! decent fuel mileage,great low rpm-5500 power also. your carb will work fine if jetted,and if any issues are repaired...so ck the comp yet? yep it sounds like lean cond? my supercoupe was doing that crap,at cruise,and i jetted the 1406 around to take care of most of it,but she has 128k,and is tired. so keep us posted,good luck,mike
