Have a near new mighty demon 650 I converted to blow threw per hangar18 mods. Only has a handful of dyno pulls and about 10 street miles. Has solid floats jet extensions non stick gaskets all the good stuff. Worked great on a hci 302 made 510 @ the tire on tims dyno i still have the dyno sheets if ud like to see how it worked. Went to a csu for the new motor so this one is just sitting around. 350 obo. Will post pics later.
