What kind of performance improvements can I expect?

The XE250H-10 camshaft is known for generating strong torque, particularly in the low to mid-RPM range. It's also designed to offer improved fuel mileage and a smoother idle compared to many stock camshafts.

Do I need to replace my valve springs with this kit?

Product Details

If you're looking to get more torque and better mileage out of your Pontiac V8, this COMP Cams Xtreme Energy camshaft and lifter kit is a solid option. It's designed for Pontiac 265 to 455 cubic inch engines, covering a wide range of classic models like the Firebird, Grand Prix, and LeMans, as well as Buick and Oldsmobile applications from the late 70s and early 80s. This kit aims to give you a noticeable bump in low-end and mid-range power without sacrificing too much drivability.

The XE250H-10 camshaft features a 206-degree intake and 212-degree exhaust duration at .050 inch lift, which is a popular grind for achieving strong torque and an improved idle quality compared to stock. This hydraulic flat tappet design means it's a straightforward upgrade for many older Pontiac V8s. COMP Cams includes everything you need to get started, like the camshaft, lifters, assembly lube, and instructions, making the installation process smoother.

When installing a new camshaft, it's always a good idea to check your engine's oiling system and consider replacing valve springs if they aren't matched to the cam's specifications. This kit is a well-built choice for drivers who want a more responsive feel from their classic V8 without going to an extreme setup.
