Welcome to the site madammarty.
I had a 51 five window a few years back with a 350/400 combo. There are several members building AD pickups, suburbans and panels on this site. Check out the Project Journals section of the site for the members builds. As well use the Knowledge Base and the search function for quick answers to your questions. Here are a few links I have collected over the years:
Glad to have you here and enjoy the site.
