LS Engine to Big Block Chevy Electric Water Pump Adapter Plates     These adapters are designed to use the much cheaper (approx $96 on ebay, part # E-5927-P shown) BBC electric water pump on LS engines. 

Made in the USA from 5/8" thick aerospace grade billet aluminum
  Includes: Bolts, Gaskets, and 2 adapter plates with -12 ORB

On the top 2 holes of the adapter plates, these 2 holes use -12 ORB threaded fittings and should be combined with a "Y" block then transfered to the radiator.
Some applications may require 3/4" NPT extension to clearance hose around crank pulley.



Natural aluminum finish as shown
