By Fergus Ogilvy –
Olive Branch, MS: Lunati makes available their Pro Series 6.300-inch connecting rod. It is designed for all aftermarket LS large displacement racing blocks with 9.500 to 9.750-inch deck heights. They fit all LS blocks and, naturally, suit Lunati’s Pro Series LS long-stroke crankshafts.
Their chief advantages are two-fold. First, when compared with the 6.125-inch con-rod, their longer length provides essential crankshaft clearance, eliminating the necessity of cutting away valuable counterweight material and the subsequent headaches and extra costs involved in rebalancing. Second, the 6.300in-long rod restores a more desirable stroke-to-rod ratio. Further, it retains the correct compression height for the piston.
Derived from 4340 alloy steel, which is oil quenched, tempered, and tested, these connecting rods were created to handle more power and more rpm. Though they are designed for race engines, they’ll serve in any LS block where a stroke length of 4.125 inch or longer is desired.
Weighing 645 grams, they are sized on the big end for 2.100-inch crank pins and on the small end for 0.928-inch piston pins and equipped with ARP2000 series rod bolts.
Lunati also makes a full range of Pro Series 4340 alloy steel connecting rods for small-block Chevrolet engines.
