cam ideas

its going in a 1970 duster and so far we have decided to bore it 0.020 and shave the deck to 0.030 i want to put a stall converter on it re size the valves too put a 4 barrel carb on it. for now i am thinking a 2 1/4 inch exahst pipe on it with prolly a cherry bomb muffler all the rest of the stuff will be decided after i pull the engine today oh and idk whats in it for a transmission i find out when i pull it out today and i will post it but i was just wondering what the most popular cam people put in it is. i wont be drag racing it or anything i would like to keep it at around 15mpg and have a nice choppy snotty sound thats reisonably loud
