What would you guess about the Hemi? I had a friend with a ‘66 Belvedere Hemi. Play with the tune, timing, etc, add a set of headers and BINGO! somewhere around 550 HP.

The old Hemi was rated at 425 @ 5000 rpm or probably about 475 hp at peak rpm. Given that these ratings were on a test platform at optimum (not street) tune, without exhausts, water pump, etc, I seriously doubt you were getting 550 at the flywheel.
My Mustang weighs about the same with 435 hp and has better quarter mile times and top speed.
