LT1 Water Pump Adapter

Unbalanced Engineering Water Pump Adapter Plate

We have machined an insert for the LT1 water pump to allow the use of a Stewart Pro Series cartridge (STE50003). They are made from 5083 Aluminum for corrosion resistance. The Steward Pro Series race water pumps will flow more than the stock unit and allow the use of a double roller timing chain.
