What is a 'retro-fit' hydraulic roller camshaft?

A retro-fit hydraulic roller camshaft is designed to be installed in an engine that originally came with a flat tappet camshaft. It allows you to upgrade to the benefits of a roller valvetrain, such as reduced friction and increased durability, without needing to change the entire engine block or cylinder heads.

What kind of idle sound can I expect with this camshaft?

This camshaft is described as having a 'slightly noticeable lope at idle.' This means you'll hear a bit of a rougher, more aggressive idle sound compared to a stock camshaft, which is often desired for a performance look and feel.

Does this camshaft come with lifters and pushrods?

This product listing is for the camshaft only. To complete the installation of a retro-fit hydraulic roller camshaft, you will typically need to purchase compatible hydraulic roller lifters, pushrods, and potentially valve springs and retainers separately.

Product Details

This COMP Cams C43 270H-R10 camshaft is a retro-fit hydraulic roller camshaft designed for V6 engines originally equipped with a flat tappet cam. You'll receive the camshaft itself, ready for installation into your Chevrolet or GMC 4.3L (262 cid) V6. This camshaft is intended for those looking for mild street performance, and it's designed to work with your stock torque converter, making it a straightforward upgrade for many applications.

The C43 270H-R10 camshaft features a 215/215 duration at .050 inch lift, which is a popular choice for a noticeable, yet still manageable, idle lope. This characteristic sound lets you know there's something a bit more potent under the hood. While it works with your stock converter, COMP Cams suggests pairing it with an aftermarket intake manifold and headers, along with a gear ratio between 3.40 and 4.10, to really unlock its potential. This camshaft is specifically for carbureted engines and is a great way to wake up your 4.3L V6 for improved street driving.

This camshaft fits a wide range of Chevrolet and GMC trucks and vans, including popular models like the Chevrolet Astro, S10, and GMC Safari. It's a solid option for anyone wanting to add a bit more personality and performance to their V6 engine without going overboard.
