Six-time NHRA Pro Stock world champion, Warren "The Professor" Johnson, runs DRCE, why don't you? This family of blocks was specifically designed for 500 cubic inch Pro Stock drag racing competition. The camshaft has been raised, the distributor hole has been moved, and the bore spacing allows for the preferable big bore with short stroke pistons and crankshaft for enhanced performance. The big bore design unshrouds the heads so you can run bigger cylinder head valves and get more air into the engine. Even the head bolt holes are not drilled, so either Pontiac S/D, Olds DRCE, or Chevrolet bolt pattern heads can be used. Our DRCE 3 block is the latest Pro Stock block that features a raised camshaft, lighter weight, and the latest evolution of Pro Stock design from some of the best racers in the world. All of these blocks are sold "solid", without the lifter or head bolt holes drilled and tapped, which allows Pro Stock race teams to design their own specific locations for maximum power. Whatever it takes to make you a champion, Chevrolet Performance Parts is there!
