Colton-K10

alright so i have a 1980 k10, 5.7 350ci and im really wanting to get a new camshaft one that will make it sound alot more 'badass' but i have no idea where to start, i have a remotely stock 350ci, i have an edelbrock intake, holley four barrel carb, preformance headers, and a hei msd distributer, i really have no idea about this subject i have a th350 auto tranny with a np203 tcase, i want the loud cam loping sound, im not looking for crazy preformance gains, id rather not loose alot of performance but its mostly streer use, when i had my plugs changed the guys said i was running a really rich fuel mixture, sooo where do i go from here?
