Another fine suggestion ^^^^^ adjustments easily made with metering rod swaps and jet swaps.

I have a quickfuel (780) carb on my 440, and first put one on my stroker 408. The carb that came with the engine was a 750 but had no ability to tune things without major work. With a few little tweaks the QF carb woke those engines up and put a smile on my face. I will never use another Holley style carb that cannot be tuned with IAB/HSAB and PVCR changes.

Remember: engines/drivetrains are a system. It is important to make changes intelligently so that the system works together to do what you plan doing with the vehicle.
