Disappointed in my 383 on the Dyno

I do agree. The numbers aren’t bad. And a cam change itself isn’t going to get u to 400 at the wheels. Could get u closer though. I thought cam was hydraulic rpm. Guess I read wrong.
I was told it is a hydraulic roller cam from edlebrock to go with the top end performer rpm kit. The shop i had it at yesterday that did the dyno tuning said its a very mild cam. I know it would be better if i knew the specs of the cam but without tearing it apart, giving you guys what i know is all i can do.
