I had the chance to talk to the Holley rep at the show and got a very cool demo on the unit. Very impressive. Also the new Hot Rod magazine has an article towards the back of the issue with some more info. When I get a chance, I'll dig through the 2 milk crates worth of info I picked up and add some more information to this. One thing, yes its not cheap, but its less than spending big coin on a fabbed and heavily baffled tank. Pick your poison.
