RAYLAR HO 750 ENGINE

Raylar has developed and now manufactures a new GEN VII 600 cubic inch big block engine that uses an enhanced version of Raylar’s “Big Power” aluminum cylinder head, a special GM racing extreme duty cylinder block and Raylar’s own electronic injection IR stack injection manifold.

This engine produces an amazing 765 HP and over 825 FT/LBS of torque with 89 octane pump gas with a 700 RPM idle and a reasonable rev limit of 5600 rpms.
This is done without the engine life shortening use of high service level of supercharging. The Raylar HO750 engine is provided as a complete engine equipped with all pumps, alternator, starter, ECM, harness, sensors, pulleys, fresh water (closed cooling) and a polished stainless water cooled headers for a complete builder or installer package.
Raylar has also teamed with Konrad Outdrives to provide this engine in a complete ready to run engine/drive package with Konrad’s incredibly strong, reliable and affordable ACE drive package.

This Raylar HO 750/Konrad ACE package represents one of the high performance marine industries most affordable, powerful, reliable, turnkey naturally aspirated engine drive packages available today.
