Disappointed in my 383 on the Dyno

Could use a lot more camshaft

Performer RPM cam (even the flat tappet) is far from a stock cam:
  • Lift: .480''/.495''
  • Duration @ .050: 238°/246°
  • Advertised Duration: 300°/308°
  • Stock 383 roadrunner 4bbl was .450/.468 lift with 268/284 duration The duration at .050 lift is 214/225
But still pretty mild by todays standard

Any cam you would recommend with hydraulic lifters and 1.5 rollers up top? I know, without knowing the rest its hard to really make a reccomendation but to just get me in the ballpark to focus my research and limited time would be appreciated. I love this forum, you guys are beyond helpful
