Do these lifters come with a hydraulic roller camshaft?

No, this kit includes only the hydraulic roller lifters. You will need to purchase a compatible hydraulic roller camshaft and pushrods separately to complete the conversion.

Can I use these lifters in any Big-Block Chevy engine?

These lifters are specifically designed for 1990 and earlier Big-Block Chevy Mark IV engines that originally came with conventional (flat-tappet) lifters. They are intended as a retro-fit solution for these specific applications.

What is the benefit of using hydraulic roller lifters over flat-tappet lifters?

Hydraulic roller lifters significantly reduce friction within the valvetrain compared to flat-tappet designs. This allows for more aggressive camshaft profiles, higher RPM operation, and generally improved engine efficiency and performance.

About this part

Product Details

If you're working on a Big-Block Chevy Mark IV engine from 1990 or earlier, and you want to upgrade to a hydraulic roller camshaft system, this Edelbrock Retro-Fit Hydraulic Roller Lifter Kit is what you'll need. These lifters are specifically designed to work in engine blocks that originally came with conventional, flat-tappet lifters, allowing you to make the switch without needing a factory roller block. This kit is sold as a complete set of 16 lifters, enough for a full engine rebuild.

Edelbrock has engineered these lifters for high-rpm power and street performance. They feature precision self-aligning capabilities, which helps ensure proper camshaft operation and reduces wear. The roller design itself is key to reducing friction compared to flat-tappet lifters, which can allow for more aggressive camshaft profiles and improved engine response, especially at higher RPMs. This is a well-built component designed to handle the demands of performance applications.

This kit is a solid option for anyone looking to get the benefits of a hydraulic roller setup in their classic Big-Block Chevy. It's important to ensure you have a compatible hydraulic roller camshaft and pushrods when making this conversion. Always refer to the manufacturer's installation instructions for the correct procedure and any additional components required for your specific build.
