This was a fun project to build. Top quality parts throughout. Dart aluminum block, forged internals, GM aluminum heads, TPiS custom solid roller camshaft, Jesel rockers, and an ARE 4-stage dry sump system. This is a legal road race engine for Brad Hoyt's vintage 69 Corvette road race car. 640hp @ 6500rpm and 540lbs/ft @ 5600rpm.
