Do these lifters come with the necessary hardware for a flat tappet to roller conversion?

No, these are the OE-style hydraulic roller lifters themselves. If your engine originally had flat tappet lifters, you will need to purchase the COMP Cams Retro-Fit Kit separately to complete the conversion.

What is the main advantage of using roller lifters over flat tappet lifters?

Roller lifters significantly reduce friction in the valvetrain compared to flat tappet designs. This leads to improved engine efficiency, increased component longevity, and the ability to run more aggressive camshaft profiles.

Are these lifters suitable for high-performance camshafts?

Yes, these hydraulic roller lifters are designed to handle more aggressive camshaft profiles than traditional flat tappet lifters. This makes them a good choice for performance builds where a more radical cam is desired.

Product Details

If you're looking to get more out of your Ford small block, especially if you're rebuilding the top end or upgrading from a flat tappet setup, these COMP Cams OE-Style Hydraulic Roller Lifters are a solid choice. They're designed to work with factory roller cam blocks or can be retrofitted into earlier flat tappet blocks using COMP Cams' necessary hardware kit. This means you can get the benefits of roller lifters without needing a completely new block.

These lifters are built to reduce friction compared to traditional flat tappet designs, which not only helps with overall engine efficiency but also contributes to increased longevity. They can also handle more aggressive camshaft profiles than flat tappets can manage, giving you more options when choosing a cam for improved performance. With a standard .875" diameter and a seat height of 2.60", they are designed to fit within the specified Ford small block applications, including popular engines like the 5.0L and 302, as well as 351W, 351C, 351M, and 400M variants.

This set is a popular upgrade for a wide range of Ford vehicles, from classic Broncos and F-Series trucks to early Mustangs and Explorers. They offer a noticeable improvement in how the valvetrain operates, especially when paired with a suitable roller camshaft.
