What did your dyno hp curve look like. Did it take a big dump at about 5500? Are you using original style mufflers? If so, you might be suffering the problem many panteras have with a restriction in the exhaust. Before you do anything else, you might want to try taking the mufflers off and running open headers for a dyno run. I suspect you can then pull to 7 grand. My car and my friends cars that pulled high rpms all ran the Hall Big bore exhaust.
