You have a definite carb problem and I suggest you find a book like the one I posted or similar and read it from cover to cover. The one I posted explains in great detail how to tune a Holley carb.

I found the book on Borders website for $14.95 and I would assume it's available at other book stores.
From what you have posted it seems to me that your carb needs a complete rebuild and I'd stress boiling it out and make sure all the passages are clean and clear of any crud. As has been suggested earlier that carb could be too small for your application and IMHO it's also the wrong carb. DP's and automatic trannies on the street don't work well together, it's too hard to control the secondary tip in. If it were mine I'd opt for an 850 vacuum secondary Holley as I'm not a huge fan of Carter/ Edlebrock.
