The cam makes the sound,so more cam you put in it the more radical it will sound.The smaller the cam the tamer it sounds.If you want that real thumper ground pounder sound you want lots of duration and a tight centerline,i.e 290 dur with a 108 centerline.But you can play with a cam and do the same cam on a 114 centerline and tame it down some.
Also headers play in to the sound with longtubes vs shortys,and equal length primaries.
Then collectors,and h-pipes,then mufflers.
So there is alot to making sound.
