What is a 'drop-in' lifter?

A 'drop-in' lifter means it's designed to fit directly into an engine block that was originally manufactured to accept hydraulic roller lifters, without requiring modifications to the block itself. This simplifies the installation process considerably.

Do I need two sets for a V8 engine?

This set contains 12 lifters, which is the correct amount for a V6 engine. For a V8 engine, you will typically need two sets to have the required 16 lifters for your application.

What is the benefit of a short travel lifter?

Short travel lifters have a reduced internal plunger travel distance. This can lead to a more stable valvetrain, quicker response to camshaft lobe profiles, and potentially less need for valve lash adjustment compared to standard travel lifters.

Product Details

If you're working on a GM V6 or a Small Block Chevy engine that originally came with a hydraulic roller camshaft, these drop-in hydraulic roller lifters from COMP Cams are a solid choice. They are specifically made to work with OE roller blocks, meaning they're designed to fit right in without needing any modifications to the block itself. This makes them a straightforward option for rebuilding or upgrading engines like the 4.3L V6, or popular Small Block Chevy displacements from 265 up to 400 cubic inches, including those found in classic Camaros, Corvettes, and C10 trucks.

These lifters feature a short travel design, which is a key aspect of their performance. A shorter travel distance means less valve lash adjustment is needed and the valvetrain can respond more quickly to camshaft lobe profiles. This can lead to improved engine response and a more consistent valvetrain operation, especially at higher RPMs. COMP Cams is well-known for its engine building components, and these lifters are built to meet the demands of performance street engines. They are made from durable materials designed to withstand the rigors of regular use and provide reliable performance over time.

When installing these lifters, it's important to follow the manufacturer's recommended break-in procedure to ensure they seat properly and achieve their full lifespan. You'll also want to make sure your camshaft and pushrods are compatible with hydraulic roller lifters. This set includes 12 lifters, which is the correct quantity for a V6 engine; for V8 applications, you would typically need two sets. Ensure you have the correct quantity for your specific engine build.
