Disappointed in my 383 on the Dyno

ok, so I actually reached out to the kid of the guy who owned the car prior to me and he stated it wasn’t a edlebrock cam after all and he’s almost positive it’s the cam below as that’s the box that was I the garage. See below

Crane BBM Hydraulic Roller Cam HR-222/339-2S-12
  • Camshaft
  • Hydraulic Roller
  • Lift 0.509 / 0.528 in
  • Duration 284 / 292
  • 112 LSA
  • 2200 / 6400 RPM
  • Mopar B / RB

Hope this helps to give you an idea of where I am at
Nice street cam but that is not going to give you the panty dropping power you are after.
