"I can't say enough about RGR Engines," Phil says. "His (Rich) knowledge can't go without thanks." Rich Groh screwed together a 383ci Windsor using a 351 Lightning block. "Here is a block, what can we do?" asked Phil at the outset of the project. Rich answered with a steel crank, stock rods, and RGR Engines-spec Diamond pistons. He topped the short-block with FRPP Z304 heads, an Edelbrock Super Victor intake with a Wilson Manifolds elbow, and 25 pounds of boost courtesy of a ProCharger D-1SC supercharger. The combo made an effortless 715 hp at the rear tires.
