Welcome to the forum, nice to see a Poncho guy on board. I had a 63 Bonneville, and always liked the 63'-64's a lot. Too bad they've gotten so pricey or I'd have another one. As for the Holley question, not sure about any specific thread, maybe do a search, but we have some very knowledgeable motor guys on here who I bet can help you out. (Once they wake up for the day )
