Disappointed in my 383 on the Dyno

this could be part of your problem. These days you have to check the heads for problems, that means take them apart. I've seen many aftermarket heads at my buddies shop that were new and they had problem like seat run out, tight guides etc. He checks all new cylinder heads before installing them

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

Hydraulic Roller
Lift 0.509 / 0.528 in

Hope this helps to give you an idea of where I am at
