Mercury Racing has partnered with Roadster Shop to bring the revolutionary SB4 DOHC engine to the custom car market, available exclusively through the Roadster Shop. Based on the GM LS7 engine block, Mercury has developed a dual overhead cam, four-valve head to take the LS platform to the next level. The four-valve head allows for significantly improved intake and exhaust port flow over the traditional two-valve design, resulting in improved driveability and idle quality in a package that revs to 8,000 rpm and makes 750 hp.

If you’ve been waiting to pull the trigger on electronic fuel injection, Summit Racing’s MAX-efi 500 Fuel Injection System makes converting from a carburetor to EFI virtually a no-brainer. The MAX-efi 500 features a four-injector aluminum throttle body that bolts to most four-barrel carburetor intake manifolds and uses the factory-style throttle linkage. The throttle body has integral fuel rails and also houses the Temperature Manifold Absolute Pressure (TMAP), intake air temperature, and throttle position sensors and the idle air control motor. The self-tuning ECU continually adjusts fuel delivery to provide the optimum air/fuel ratio under all climate and altitude conditions.
