With combustion chamber volumes of 85cc (Milling from 75-83cc possible for $250) accompanied by 132cc exhaust ports, AFR's new 280cc is the ultimate choice for up to 477 cubic inch engines operating up to 6200 RPM. AFR's trademark 3/4" thick cylinder head deck makes them ideal for heavy nitrous or blower applications.
