Thanks for the links, but I have a feeling I'm going to keep the EFI 302 in it for MPG purposes and just do what I can to get the most budgeted power out of the sedan-firing-order 302. (Researching what it would take to switch to HO firing order, but would also require an entire mass air assembly and new cam...)
Then later, for power, I'll just get a Mustang (coupe, convertible, or T-tops) and put as strong of a naturally-aspirated engine as the chassis will support, depending on which model I get.
Do keep us updated on your build, though, because I am sure a N/A motor won't satisfy me forever...
