Though I can't comment about it's intended use as I modified it for another engine, it's a collection of quality parts that are needed for driving a pump. Quick shipping and typical excellent speedway service is icing on the cake.

Poor Machining Tolerances

Neither the woodruff key or the key stock that was provided with the mandrel fit into the machined keyways. Also, the od on the mandrel that fits into your balancer/pulley bore was too large. I spent about an hour sanding down the key's and mandrel before I could install it.

This gives you the ultimate flexibility for pulley size and spacing, whatever water pump you use or any other accessory for that mater. I needed a very small pulley for my vacuum pump and this did the trick.
