need help asap what carb for my motor 600 750?? edelbrock

If most people could even explain why they want this brand over that brand I would be amazed.

I know why I like what I like.

If your heart is set on an edelbrock, then so be it....get the 750 and tuning kit..because right out of the box you will need to start tearing into it, changing rods and springs 'just to start.

the closet to good to go eddy carbs that I have run have all been the 600 1405-1406, even then the 1406 needed the minimum of a rod/jet combo spec'd for the 1405......the rest '750 & bigger' have been really lean ootb and short on transition.

good luck and have fun learning
