318 camshaft

Well I for one like the sound of your mopar. I would just crank the idle speed down some.
But I just gotta say; swapping in a bigger cam for the sound? Um that might not be such a great idea. If the car doesn't go as quick as the sound implies, then you have built a poser, and will get no respect. If it does go as it sounds like it might, then you have built a race car, and they don't do so good around town. If you build a snappy streeter with something like a 220 to 230* cam(050s), then it won't sound like much, but if well thought out and matched, will accelerate like the proverbially scalded cat from zero to the speed-limit, or 65 here in Canada! Yours sounds to me like it can do that right now?
