I would reconsider your cam choice. Short stroke, low compression, slow moving/large adv. duration cam - makes for very soft bottom end power. Pretty easy to make better one of these.
wit hthis , the torker is all wrong for that engine as it the cam , if the car was a 4 speed with more gearthen that cam would dork ok , i ran that cam wit hthat gear in a 130k 383 2 bbl engine with a 4speed , it wasn't a barn burner but it was ok.
The build you have laid out is why 383's get a bad rap , use a big cam with a poor single plane intake and it's going to be a dog. What heads do you have ?
