This supercharger came with a car I bought. It was bolted on to a small block chevy engine that had a hole in a block. Fully operational according to the previous owner of the car but I never heard it run or saw it in action so it wasn't tested. I can only judge by the whole in the block that it was working quite well.I installed my turbo setup and have no use for this supercharger. The bottom plate that has the model number is not really visible so I don't know the exact model number.
