What kind of idle can I expect with this camshaft?

This COMP Cams Magnum 260/260 camshaft is designed to produce a noticeable 'race idle,' which is a more aggressive and lopey sound than a stock camshaft. It's a characteristic often desired in Pro Street and race applications.

What supporting modifications are needed for this cam kit?

To effectively use this camshaft, you'll need a minimum of 10.5:1 compression ratio. For automatic transmissions, a torque converter with a stall speed of 3500 RPM or higher is recommended to keep the engine in its power band.

Does this kit come with everything needed for installation?

The kit includes the camshaft, lifters, assembly lube, and decals. You will need to source other items such as valve springs, retainers, pushrods, and potentially timing gears or a timing chain, depending on your specific engine build and requirements.

Product Details

If you're building a Pro Street Pontiac or a race car that sees limited street use, this COMP Cams Magnum 260/260 solid flat tappet cam and lifter kit is a solid option. This kit is designed for Pontiac 265-455 V8 engines and is known for its aggressive idle sound, often referred to as a 'race idle'. To get the most out of this camshaft, you'll need a minimum of 10.5:1 compression and a 3500+ RPM stall speed torque converter if you're running an automatic transmission.

This kit includes the camshaft, lifters, assembly lube, and decals, so you have the essential components to get started. The solid flat tappet design means it requires more frequent oil changes and careful setup compared to hydraulic lifters, but it offers a more direct feel and can handle higher lift profiles. It's a well-built component for those looking to push their Pontiac V8's performance envelope.

Remember that this camshaft is intended for performance applications and may not be suitable for daily drivers due to its aggressive nature and specific requirements for supporting components. Always refer to the included instructions for proper installation and break-in procedures.
