COMP Cams Camshaft LT1 280XFI HR-13

If you're looking to get more power out of your LT1 engine, especially in the mid-range and at higher RPMs, this COMP Cams 280XFI HR-13 camshaft is a solid choice. It's designed to wake up your engine for applications like performance street driving or track use, where you need that extra pull when you get on the throttle.

This is a hydraulic roller camshaft, meaning it uses roller lifters to reduce friction compared to flat tappet designs. The XFI series is known for its aggressive lobe profiles, and this particular grind, the 230/236 HR-13, is optimized for strong performance from the mid-range all the way up to the top end of the RPM band. You'll notice a more pronounced idle, which is typical for cams of this size, and it really lets you know the engine means business. To really take advantage of what this camshaft offers, you'll need to pair it with supporting modifications. The manufacturer recommends headers, a gear change (like a 3.73 or 4.10 ratio), a torque converter with at least a 2200 RPM stall speed, and a custom-tuned computer to get the most out of the improved airflow and timing.

This camshaft fits a wide range of popular GM rear-wheel-drive vehicles from the early to mid-90s, including models like the Chevrolet Camaro, Pontiac Firebird, and Buick Roadmaster. It's a significant upgrade for anyone serious about extracting more performance from their LT1-powered car. Remember, this camshaft is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper setup and break-in procedures.
