  • The Xtreme Energy XFI™ Cam Lobe Series is designed for use with modern induction systems, heads, springs and rockers. The XFI™ intake lobes have more lift than the base Xtreme series, and the XFI™ exhaust lobes have more area under the curve, for better exhaust flow, than the base exhaust series. These are the first hydraulic flat tappet profiles designed for use with COMP Cams® Beehive™ Valve Springs, such as the #26915, #26918 and #26120. The combination of these profiles, the Beehive™ Springs, and our Ultra Pro Magnum™ Rocker Arms in higher ratios, makes for the most revolutionary improvement in hydraulic flat tappet design to date by bringing the latest race winning technology to the street.


1: Cams for '55-'57 engines can be custom ordered. Please Call, Email, Twitter or Live Chat for details.

2: The '87+ Chevy Small Block received provisions for roller lifters. Most '87 - '93 GM cars came with roller lifters, but most '87 - '95 trucks came with flat tappet lifters in roller lifter style blocks. If a roller cam is desired and your block has OEM-style roller cam provisions. COMP Hyd. Roller Lifter Install Kit for '87-'90 Blocks or '91-'02 Blocks can be purchased, as well as a '87+ OE-Style Hyd. Roller Cam and '87+ OE-Style Roller Lifters. Roller cam conversion in pre-'87 blocks requires Retro-Fit Hyd. Roller Cam and Retro-Fit Link Bar Lifters.
