Finish my recipe for me?

So I'm about to start getting together the last of my bits for my 360 swap into my '64 Dart. I've got a few blanks I need filled in. The plan for this car is a fun daily driver/cruiser. Not a race car or a miser but somewhere in between.

The engine will be backed by an A833 OD and an 8.25" rear with 3.55s an a SureGrip.

The current engine specs are as follows:

-'70 cast 360 block
-.060" over SpeedPro Hyperutectic H116CP 0.010" in the hole (9.8:1cr)
-Stock crank and rods
-Double roller timing chain
-Stock cast 587 J heads, rebuilt with hardened seats and SS 1.88"/1.60" valves
-Comp valve springs and lifters
-Comp 268H cam (.454 lift 268dur, 218dur @ 50)
-Wieand ActionPlus dual plain intake
-Doug's D450 headers

The pieces left in the puzzle are:
Carb size-650cfm or 750cfm?
Cam size- should I go bigger?
Valve size- should I bother swapping the 1.88s for 2.02s?
Clutch- what kind should I get?

Thanks for the help guys!
