Ok thanks for the input. Do you guys think that a MP T76 is well suited (especially considering that a 6.0 will end up built for it)....or do you think I am better served by a MP T70....How does my parts list look for the bulk of it?...Thanks

With the 317 heads you can run 10-12psi no problem. Hell I have been running 14psi occasionally with no problems yet. You can run the same if you have a good tune and all the supporting mods as well as a good strong drivetrain.
