don't run 6-speed tuned and bolted on 5.0's from a roll - they will crush your soul.
best thing to do is to get them from a dig....
here's my car in Sep 2011 versus an M6 Mustang 5.0.
Bama Tune, steeda intake, x-pipe and 3" exhaust - 390hp/375ftlbs on a mustang dyno
Cobb tune at 16.4psi (before throttle closure), fmic and DCI's - 327hp/390ftlbs on a mustang dyno (Cobb's Facility in Austin)
from a roll i got worked pretty badly - but from a dig my second gear launches were waaaaaay to much for the 5.0 to handle.
