What type of distributor gear should I use with this camshaft?

COMP Cams strongly recommends using a melanized or nitrided distributor gear with this camshaft. Using standard cast iron or steel gears without these surface treatments will void your warranty and is not compatible.

What other upgrades are recommended when installing this camshaft?

To achieve optimal performance, COMP Cams suggests that a gear and exhaust upgrade will be necessary. You should also ensure your valve springs are capable of handling the high lift profile of this camshaft.

How can I tell if my engine block is compatible with this roller camshaft?

GM gradually introduced roller camshaft provisions starting in 1987. You may need to remove the intake or timing cover to visually confirm if your block has factory roller provisions or if it uses a flat tappet system. Many trucks and SUVs retained flat tappet cams until the mid-90s.

Product Details

This is the COMP Cams CS 268XFI HR-13 camshaft, a hydraulic roller camshaft designed for a wide range of Chevrolet Small Block engines from 1958 to 2002. It's built for EFI applications, meaning it works best when your engine's air intake signal isn't restricted by a carburetor. You'll notice a solid increase in performance, especially in the low and mid-range RPMs, making it a popular choice for street performance builds.

The XFI (Xtreme Fuel Injection) designation means this cam uses COMP Cams' latest and quickest lobe profiles, optimized for modern fuel injection systems. It features wider lobe separation angles compared to some other cams, which helps maintain responsiveness without sacrificing that crucial low-end torque. This camshaft is intended to work well with aftermarket cylinder heads and offers high lift, so you'll want to ensure your valve springs can handle it. COMP Cams recommends using a melanized or nitrided distributor gear with this camshaft to avoid premature wear and potential warranty issues; cast iron or steel gears are not compatible without this surface treatment.

To get the most out of this camshaft, COMP Cams suggests that a gear and exhaust upgrade will be necessary. While it offers ample low-end power and good mid-range pull, it's considered the largest cam suitable for use with a stock torque converter. If your engine is a 1955-1957 Chevrolet 265, you'll need to ensure the 5th cam journal has an oiling groove; contact us if you have questions about this specific requirement.
