Basically, this engine was a stock racing rebuild of an original, tired BBLM engine. No special power modification were made except for the normal attention to detail we give all our engine rebuilds. The Lucas fuel injection was gone through and the exhaust valves replaced with new original type sodium filled ones. They factory rated these engines at 480 HP @ 7200 RPM. This one made 491 HP @ 7800 RPM. Chalk up the difference to a .5mm overbore.
