What is the recommended break-in procedure for this camshaft?

Flat tappet camshafts require a specific break-in procedure to ensure proper lubrication and prevent premature wear. Always consult the manufacturer's installation instructions for the detailed steps, including initial oiling and running the engine at a specific RPM for a set duration.

What is the lobe separation angle for this camshaft?

The lobe separation angle for this COMP Cams XE250H-10 camshaft is 110 degrees. This specification influences the engine's torque curve and idle characteristics.

Does this camshaft require any other special parts for installation?

While this camshaft is designed as a direct replacement for many Pontiac V8s, it's always recommended to inspect your valve springs, pushrods, and lifters. Using new lifters is often advised with a new flat tappet camshaft to ensure proper break-in and longevity.

Product Details

COMP Cams is well-known for performance engine components, and their Xtreme Energy line is a popular choice for drivers looking to get more out of their engines. This particular camshaft, the XE250H-10, is a hydraulic flat tappet design specifically made for Pontiac V8 engines ranging from 265 to 455 cubic inches. It's designed to give you a noticeable boost in torque, especially in the lower to mid-RPM range, while still aiming for good fuel economy and a smooth idle.

When you install this camshaft, you can expect a solid improvement in pulling power, making your Pontiac feel more responsive. The 206/212 degree intake and exhaust duration at .050 lift is a common specification that balances performance gains with drivability for many classic Pontiac applications. This part fits a wide range of vehicles, including popular models like the Pontiac Firebird, Grand Prix, and LeMans, as well as Buick and Oldsmobile models from the late 70s and early 80s.

For installation, remember that this is a flat tappet camshaft, which requires careful attention to lubrication during the break-in period to ensure the lifters and cam lobes wear in properly. Always refer to the manufacturer's installation instructions for the correct break-in procedure and any other recommended parts.
