This is really a great new addition to our Ford lineup. This Hurricane manifold for 35 W engines offers many features not found in any similar manifold. It has a bridged rear water crossover passage that helps keep engine temps down. It also features injector/nitrous bosses as well as two extra tapped water ports at the back. It is available with the injector bosses machined for injectores and we also offer a set of fuel rails ( 0 0 ) designed for this manifold as well as a complete fuel rail kit ( 0 07), which includes our 0 72 fuel pressure regulator. See page 23 for specifics. This manifold will accept all standard pattern square bore carburetors. It fits standard 35 W blocks with a 9. 50" deck height. An ideal manifold for circle track or drag racing engines operating in the 3500 to 7500 rpm range.
