Stupid question, I know. There has to be better ones. I have a 350 in a 46 Chevy truck. There is a lot of movement when I accelerate, and I would like it to be stiffer. I have an idea for some trick exaust, but there cant be a lot of movement for my idea to work. Yes the current mounts are stock (looking) and not broken. Any suggestions? Drawbacks? Thanks -M
