318 build help

This is my first Mopar build. I have a 72 dart with a 318 and 727 auto. 8 3/4 rear with suregrip 323 gears. I have a Edelbrock performer manifold, Edelbrock 600 carb Shorty headers, dual exhaust. Just looking for a mild Street engine. Have a set of 302 casting heads. Will be doing new bearings and rings looking for piston suggestions I Have a summit 6901 camshaft but not sure if that’s the best option. Would like to be 300 or better horse power but just really want to burn some tires and have some reliability What do you think of this combo? Any help or suggestions would be greatly appreciated.
