edelbrock to holley conversion

I've been tuning carbs for 30+ years so I'll try to sum this up with as few words as possible. Edelbrock carbs generally run well right out of the box, very easy to tune and adjust( jets,rods,floats, pump shot), and hold the adjustments well. If you want to play with a Holley then get a complete jet kit, nozzles, power valves, pump cams and bowl gaskets and be prepared for lots of testing until you get it dialed in. You can get a Holley to run well but it's a lot of work and time. Good Luck and have fun.
