Stock 318 2 Barrel Cam Choice

So I recently bought a bone stock '73 318 2 barrel.
Since it is going to need to beat up on some stock mustangs from my high school, I am going to do a cam swap and put on a '71 340 4 barrel intake I got with the engine. My question is; since I am only changing the cam and intake, what cam would be best in terms of power and rump rump factor.

I was thinking about one of these three, but I want to see what you guys suggest.
