The Typhoon for 351W engines is a great street manifold for this engine. It provides good top end power without sacrificing bottom end torque. Its long runner, dual plane design provides the best of both worlds. This manifold performs best with an aggressive street cam. For street use a 600-750 CFM vacuum secondary or double pumper carburettor. For competition use a 750-850 double pumper carb. One major feature on this manifold not found on competitive models is a rear water crossover passage which promotes a cooler running engine.

  • Suits Small Block Ford 351W, will not suit 289/302
  • 1500-6500rpm range, ideal for a performance street engine
  • Cast aluminium, natural finish
  • Suits square bore 4 barrel carburetors and throttle bodies

Calflow manifolds are cast in high pressure steel dies rather than the pour-in sand molds used by other aftermarket manifold manufacturers. This type of tooling costs 2-3 times more than conventional sand-cast patterns, but the finished product is worth the additional expense. And because the cores (which form the internal ports and water passages) are mounted in steel instead of sand during the casting process, there is no chance of any core shift, which sometimes go undetected in sand castings.
