Engine Works Oil Restrictors
Engine Works offers oil restrictors for a variety of engine applications from the 1950s and up. Machined from aluminum, they fit in most small and big block Chevy blocks (except Bowtie) at the rear of the block. Simply replace the oil galley plugs (tapping may be required). These restrictors are not for use with hydraulic lifters. An oil restrictor installs in the oil passages of the engine block. It limits the flow of oil to certain parts of the engine. Engine oil lubricates and cools vital engine components. In most cases, more oil usually means the engine will run cooler and last longer. However, in some specific RACING applications, more oil can actually reduce the performance of the engine. When roller rockers and solid lifters are installed, the amount of oil required by the valvetrain is reduced greatly. Installing an oil restrictor kit will limit the oil flow, reducing the windage created from excess oil draining past the rotating assembly. This keeps the oil flowing where it is needed most—to the rod and main bearings.

PRW Pushrods
PRW pushrods are ideal for serious street performance and race applications. As an essential component in an engine's valvetrain system, the primary function of a pushrod is to transmit the vertical motion of the camshaft to the rocker arms. As the lobes of the rotating camshaft lift the pushrods, they push against the rocker arms, causing them to pivot and open the valves. The length of a pushrod is critical to ensure proper valvetrain geometry, therefore, it should be carefully selected to maintain the correct relationship between the camshaft, pushrod, rocker arms, and valves. Choose the PRW pushrods designed for your application needs. Key features: * One-piece construction from .080 in. wall, seamless chromoly * Heat-treated for extended durability and guide plate compatibility * Precision formed and reinforced ends * Black-oxide finished with laser etched length

Manley Piston Ring Groove Lock Spacers
Manley piston ring groove lock spacers feature a radial tension design (RTD) that prevents rotation. Should your custom Platinum piston requirements necessitate the wrist pin hole break into the oil ring groove, Manley can widen the oil ring groove and incorporate a groove lock spacer available in several sizes. Manley's RTD groove lock spacers have replaced the old-school, dimpled-style pieces. Their pistons requiring G/L spacers are manufactured with a "receiver groove" within the oil ring groove where the RTD G/L spacers snap into place. Order the proper size and quantity to meet your requirements.

Kanter Rod Bearings
Kanter rod bearings are precision-made for classic cars to support the crankshaft, reduce friction between the rod and crank, and allow the piston's linear motion to become the crankshaft's rotation. These components are crucial for converting piston movement into crankshaft rotation, fitting into the connecting rod's "big end" with a cap, and relying on engine oil for a protective film. Kanter rod bearings come as two semi-circular halves (shells) that fit into the connecting rod and its cap. They are available in standard sizes, as well as undersizes to match worn crankshaft journals, ensuring smooth rotation and proper lubrication for vintage engines.
