Product Details
This COMP Cams K-Kit camshaft kit is built around a hydraulic flat tappet camshaft with a 235/249 degree duration. This is a serious upgrade for Pontiac V8 engines, designed for high-performance street and strip applications. To get the most out of this camshaft, you'll want to ensure your engine has at least 9:1 compression, a 2500+ RPM stall speed torque converter, and is set up with a performance intake, headers, and appropriate gearing. Expect a noticeable, rough idle that lets everyone know this isn't your average cruiser.
This isn't just a camshaft; it's a complete package to get your engine breathing better. The kit includes the camshaft itself, lifters, valve springs, retainers, valve locks, and valve stem seals. You also get a timing chain set to ensure precise valve timing, plus assembly lube to help everything go together smoothly. COMP Cams even includes decals and instructions to guide you through the installation. This kit is designed to fit a wide range of Pontiac, Oldsmobile, and Buick V8 engines from the mid-50s through the early 80s, including popular models like the Pontiac Catalina, Firebird, and Grand Prix.
When planning your build, remember that this camshaft kit is intended for performance use and will result in a rough idle. It requires supporting modifications to achieve its full potential, so make sure your fuel delivery, exhaust, and drivetrain can handle the increased power. This kit is not CARB approved and cannot be shipped to California.
