Description:
The ERL SUPERDECK I 6 bolt takes our SUPERDECK I 4 bolt system to the next level for extreme applications.  The addition of two head bolt bosses per cylinder creates a block that is specifically designed to handle extremely high boost or nitrous. Our SUPERDECK I 6 bolt blocks have run successfully with over 30psi of boost and over 1500HP. The truss design of the ERL SUPERDECK I adds unmatched strength and stability to the bock and deck surface.  The truss design (shown in the pictures above) involves connecting each pair of head bolts through an aluminum truss.  This truss allows the load to be shared across the deck surface minimizing deck deflection. This allows a thinner deck section to outperform the much thicker decks. The SUPERDECK I system also allows for larger bores than dry sleeves.  The ERL SUPERDECK I is available as a 443CI engine with a 4.200” bore and 4.000” stroke.  The sleeve has a 25% greater wall thickness at a 4.200” bore than the others have with a 4.125” bore. ERL has incorporated the superior stability of the deck with optional ½” head studs to provide uniform clamping over the entire gasket surface.  A clamping force of nearly 80,000 pounds is provided by the 1/2” studs to reduce the potential of lifting the head. Traditional aftermarket Race Blocks increase deck thickness and reduce water access to the deck to aid in head gasket retention.  The SUPERDECK I does not restrict water access to the deck surface. In fact the SUPERDECK I extends the water cavity floor and emphasizes upper cylinder cooling through the trusses which are short-poured. This lowers the potential for detonation caused by hot spot in the combustion chamber.  An additional advantage of the truss system is that it ties the main saddles in the block to the deck.  This greatly increases the strength of the main saddles by changing the load path.
