Well, I suggest you fix the obvious problems first. The 5/16" fuel line you are running is too small. That blue Holley pump you are using has a 3/8" NPT on the "in" and "out" for a reason. I'm not sure what a decent CR means, but with that cam ( it is an older grind ), you my very well not be able to run todays pump gas by the time you get the DCR where it should be to make power in the 3-4 grand area.
