Holley Top Shot Nitrous setup. Full system minus the line from the bottle to the carb. Sprays a small shot (75-150 HP) of nitrous directly into the 4 barrels of a 4V carb. Includes full bottle of N20 and mounting brackets. This system has been obsolete since at least 2005 and is very hard to find now (don't ask me how I know;-)). Price is what I paid back in 2016. Ships from WA state 98272 unless local pickup (preferred). $800
