Big Breathers
CNC Big-Block Cylinder Heads
Striving to provide race level performance in a streetable design, Edelbrock now offers the RPM Xtreme cylinder heads for 427-572ci big-block applications. These feature CNC machined runners and combustion chambers whose flow is nearly on par with the Victor series professional race heads. The deck has been rolled 1.5 degrees to improve the intake and valve angle, including port velocity. The well thought out design also ensures that the 2.25/1.88-inch intake/exhaust valves still clear the factory valve reliefs. You get your choice of 300cc (oval) with 110cc chambers or 325cc (rectangular) versions with 118cc chamber volumes. All cylinder heads are hand assembled at Edelbrock's headquarters and carry a 1-year warranty. In addition, the RPM XT heads accept most stock port location exhaust headers. Installation is the same as a factory set of heads, making this an easy bolt-on upgrade.

Custom 'Sticks
Ls Cam Cores
Comp Cams is introducing three new series of custom cam cores for the LS powerplants, including the GM LS Active Fuel Management (AFM), Wide Lobe Separation, and 60mm bearing journal cores. The AFM cores are designed as replacement cams that maximize the performance of street LS engines that are 100 percent compatible with Active Fuel Management (AFM) or Variable Valve Timing (VVT). The Wide Lobe Separation LS cores target boosted and emissions sensitive applications and can handle a lobe separation angles ranging from 118 to 124 degrees. Lastly, the 60mm bearing journal LS cores feature a larger base circle for lower pressure angles (less side loading on the lifters), a stiffer core, and a lower rocker arm ratio to reduce stress on valvetrain components in race applications. Every cam using any of these steel billet cores will be custom ground for each specific application and can include options such as gun drilling.
