There is another link that I hope the moderators here won't mind me mentioning that may help with your questions. It's sbftech.com (small block ford tech).

The site is specfic to ford's and has a drag racing section, parts, SB engine, tech help, just tons of info. You may want to look at it being you want to go drag racing. One of the moderators there built a mustang named "Red Death" years ago that was supposed to be one bad ass car.
