I believe your easiest approach, considering what you have, would be to go with a small 4bbl, like the 390cfm Holley, headers, and dual exhaust. There are many brands and combos out there. Check the vendors in the links section. Don't overlook Tom Langdon of Langdon's Stovebolt. He's a nice guy and has helped a lot of folks.
Be sure to also use the search function here on the 'bolt. I know there are plenty of discussions on just this subject.
I also agree that Leo Santucci's book is a valuable resource, although most of the information applies to full race and not to warm street.
best wishes,
