Engine Rods connect the reciprocal motion of the pistons to the rotational motion of the crank. Performance engine rods, which are lighter than OE, allow for faster throttle response and acceleration. More importantly they can withstand the tension from a performance engine. Depending on what purpose your building your 1971 Chevrolet Chevelle for, the type of rod need can vary. Sport Compact Warehouse is your premier source for Performance Rods.
