I usta have a set up on my old 283 where I could pull a knob and suck ATF from a container into the maniford. It would put the pretties white smoke out the pipes and would stop any one from tailgating instantly. However it was dangerous. I found that the same effect is obtained when a valve drops in a 350 chevy motor going down the highway, but only out of 1 bank. I prefer the ATF over the droped valve. Not as costley.
