New Fast Burn Heads with Beehive Springs Add High Rpm Performance and Durability
We’ve added greater high-rpm durability to the CT400 racing engine with new Fast Burn heads that feature beehive-type valve springs and complementing valvetrain components. The beehive springs enable greater high-rpm performance and durability. They allow the engine to rev higher to make the most of every cubic inch of air drawn through it.

This brand-new, factory-sealed racing engine is based on the new ZZ5 street crate engine, but includes a racing-only 8-quart circle track oil pan, with dual kick-out design, along with a valve cover breather kit. The new, lightweight aluminum cylinder head casting – distinguished by new Bowtie logos cast into the ends – is based on the proven Fast Burn design, with large intake runners and 2.00/1.55-inch valves.

The CT400 racing engine has a tough bottom end, anchored by a forged steel crankshaft and hypereutectic pistons installed in a brand-new block with four-bolt mains. The assembly also includes an open-plenum high-rise intake manifold and 1.5:1-ratio aluminum roller rockers.

Put a “fast burn” on the competition – with greater high-rpm performance than ever before!
