360 build

Im thinking of building a 360 and the only thing im interested in is low end torque and decent sound. this will be nothing other then a street car and id like to leave it mostly stock meaning no work to the block or heads..is it possible to do a cam,intake,carb,exaust upgrade on it and get something nice? ..what kind of numbers? also whats a good 360 block out there is a good doner?
thanks for your help ..like i said this is on the cheap and want it nothing more then to smoke some tires and sound nice while im driving.
