What kind of idle sound can I expect from this COMP Cams kit?

This kit features the Thumpr camshaft, which is known for its aggressive, choppy, and thumping idle sound. It's designed to give your engine a distinct performance personality.

What else might I need to install this camshaft and lifter kit?

While the kit includes the camshaft, lifters, and assembly lube, you'll want to ensure you have all necessary gaskets for reassembly, such as intake manifold gaskets and timing cover gaskets. It's also recommended to change your engine oil and filter after the break-in procedure.

Can this camshaft be used with my stock torque converter?

Yes, this CS 283T HR-10 camshaft is designed to work with a stock torque converter for high-performance street use. However, for optimal performance and to fully utilize the camshaft's potential, COMP Cams recommends using a converter with at least a 2000 RPM stall speed and appropriate rear-end gearing.

Product Details

If you're looking to give your Small Block Chevrolet engine a more aggressive, thumping idle and improved street performance, this COMP Cams Thumpr camshaft and lifter kit is a solid choice. This kit is designed for OE roller 305 and 350 cubic inch engines from 1987 and later, specifically those with factory roller camshafts, excluding LT-1 and LS1 variants. It's a popular option for builders aiming for a high-performance street setup that still works with a stock torque converter, though it really shines with a 2000+ RPM stall converter and appropriate gearing.

The CS 283T HR-10 camshaft features a 227-degree intake and 241-degree exhaust duration, which is what contributes to its signature choppy and thumping idle sound. This grind is engineered to provide a noticeable bump in performance for street driving. The kit includes the camshaft, hydraulic roller lifters, assembly lube to ensure proper break-in, and decals for that finishing touch. COMP Cams is well-known for its performance valvetrain components, and this kit is built to deliver that classic aggressive sound and feel.

When installing this kit, it's important to follow the included instructions carefully, especially regarding the break-in procedure for the lifters and camshaft to ensure longevity. While it's designed to work with a stock converter, upgrading to a higher stall converter and changing your rear-end gears will significantly enhance the performance gains and make the most of this camshaft's capabilities. This kit is a great way to wake up an older Small Block Chevy and give it a distinct personality.
