LS3 Timing Chain and Gears, 3-Bolt Cam, Double Roller, Billet Steel Sprockets

When installing a double roller timing chain and gears in an LS engine, the oil pump is spaced out from the block for clearance. On most applications, this will create a clearance issue between the timing cover and oil pump. Test fit and grind as needed for clearance, before final assembly.
