edelbrock to holley conversion

Go ahead and try it! You can always take it off and switch back. Be sure to use the mopar holley throttle lever extension, makes it a lot easier to hook up the linkage. I have a Holley 650 DP on my 340, I have a big cam, M-1 intake with a 1/2 spacer, 4.10 gears and a 4-speed and the carb works awesome!! Maybe you could describe your engine and drive combo? So what if you have to monkey with the Holley carb, atleast you will learn something new. Is the carb new? I would also get some of the "blue" reusable bowl gaskets if you don't already have them, makes things easier if you have to change jets.
