well,now that the previous posters have given you lots of great "holley" advice,lets get back to your "edelbrock" carb.lol.
do you have a fuel pressure regulator in-line? if not,you need one. set it at 5psi. where are your mixture screws set? turn them all the way in,and turn them out 1 1/2-2 turns and start there. timing should be 12-15 degrees initial and all in around 2200-2400.
