Race Series 11 Little Chief CNC

Race Series 11° Little Chief CNC



Maximum competition, off-road trucks, comp/modified drag racing, circle track. 8,000+ RPM, alcohol or nitrous, turbo, supercharger.

Dart’s 11° Little Chief CNC is the ultimate small block cylinder head. Designed with Pro Stock style oval ports, big block style canted valves and “semi-hemi” style combustion chambers, the Little Chief is a radical departure from traditional small block heads.

The huge flow resulting from the 11° valve angle and splayed valve layout combined with spread oval intake ports, raised runners and highly efficient combustion chambers deliver amazing power!

It is recommended that you contact a Dart technical representative before placing an order for this item. Detailed information about your planned engine build will help to ensure that you choose the right configuration for your motor and that any special parts and considerations are taken into account.
