Allright guys I need some of your honest and expert opinions on my engine combo I built in 2001in my 66 mustang.

Engine:
Roller block 5.0 .030
Edelbrock performer heads
Victor jr. Intake
650 speed demon carb.
X303 cam
T5 tran.
9in. Rear 3.50 31 spline axel
I would like to replace the cam,intake, and ring and pinion but I'm not sure what to do and need you help on it and how much hp should this combo makes?
