Carburetor choice

i know im gonna stir the pot with this one and probably blow it up, but i have some questions..

i have a 360 in a heavy car.. it has stock bottom, whiplash cam, aluminum heads, eddy performer intake, long tubes, rev man 904, 3;55 gears... i currently run a Edelbrock 1405(600 CFM) i have never ran anything else... i have always wanted to try a Holley in some form, but there is so many choices.. mechanical, vacuum secondary's. single or double pumper, front floats, side floats, 600-650-670-750,770 cfm, 4150/4160, traditional, brawler, quick fuel, demon... so many... i don't even know where to start in choosing a Holley to try on my car.. its just a street car.. i don't want to go to big or be too small. i would like something that's fairly easy to rebuild or tune starting out as I'm going to be learning the Holley.. what are your guys thoughts?
Call Holley, they are very friendly and discuss which is best for your operation.
