ERL SuperDeck II: 500 Cubic Inch
The ERL SUPERDECK II system takes an ordinary GM LS engine and creates a 500 Cubic Inch, 8.2 liter monster.  A 4.200” bore and 4.500” stroke are obtained through the use of ductile iron sleeves, an aluminum deck plate, and extremely precise CNC machining. ERL SUPERDECK II 500CI has proven to be an extremely reliable large displacement, large stroke engine by simply following good engine design principals.  The sleeves are designed with enough length to support the piston at BDC, the rings are designed to provide high performance use without sacrificing longevity, the sleeves are made of ductile iron to prevent cylinder distortion, and finally the sleeves are machined using precision equipment and careful quality control.  The ERL SUPERDECK II 500CI is only available as a short block assembly.  The design of the rods, camshaft, and block machining has been completed to ensure proper clearance between components. Off the shelf parts will not work.  Furthermore, ERL uses only the highest quality race parts in its short block assemblies.
