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?
