When you're setting the timing you're pulling the little spout out correct? Otherwise it's going to be WAY out.
The 5.0 mustangs have a rubber center section on the harmonic balancer that likes to spin, which makes it make it impossible setting the timing using the harmonic balancer. Try setting with the spout out to get it close. Plug the spout back in and bump it up just a tad (advancing it).
Other than that, check the fuel pressure an make sure you're good there.
Also check and make sure you have the plug wires on right.
Oh, and of course check for vacuum leaks and things that aren't plugged in.
