I use one on my small block and have been happy with it,it is the same motor used on the electric water pumps they sell.Nicer setup than the old "fan motor" type Moroso I replaced,in my opinion.Came with a billet mount instead of the cad plated steel one also.Just remember when wiring it,mine ran backwards at first because it was made to be run on their water pump,so it used to be mounted facing the engine,instead of how it is mounted on the bracket.Just wire it accordingly.
