67 camaro 327 vette engine

[Kennymax]

So what would you guys do? My 67 convertible camaro has a 327 with a pretty aggressive cam. I'm putting a holly 650dp on it. What should I or could u do to make this car act preform and sound great. 90% city 10% highway driving. And with out going crazy what's the avg HP to be expected. " I don't know the exact cam"
