This rod is designed to give you the most rod length you can get with the stock block and crankshaft by using the shorter compression height Wiseco 1982P140, or a JE EXF4500-140 piston with approximately .090" cut off the top. This piston uses smaller,.490" wrist pin which is a much lighter combination than stock. The increased length lessens the rod angle at half-stroke which decreases stress on the rod and piston to wall pressure. These features provide considerable improvement in durability as well as increased performance.
