Good thing there are lots of ford stuff around.
My suggestion would be to use a 86-92 used short block. That way you could get the rollercam block and factory forged pistons. However the older blocks are alot stronger, more material cast in. I know the E7TE head castings aren't the greatest, but I have read that you can get a few extra ponies by milling them and removing the emissions bump in the exhaust track. You could do the porting at home. A super cheap set of headers would be the ford factory 5.0 tubies. Again not the greatest, but better than cast logs. I believe that the 85 mustang 4 bbl intake was made from aluminum and was better than most factory intakes, at least it has the holley flange. This is where I would start on a super budget.
