School me!

Ok, I am running a 74 Duster and a 727. I have a Ford 9" rear with 3.89 posi. I have sub frame connectors.
It does not have to be the fastest machine out there, I just want it quick. When I want speed I want it to be there, plus be able to be driven quite often on the road and still be on 93 octane.

thanks for the links
