Hurricane Small Block CHEV Single-Plane Intake Manifold, HI-Performance, SBC

This manifold has long been the leader of the pack for single plane manifolds for Small Block Chevy's with 23 degree cylinder heads. This manifold has consistently outperformed all of the well known brands which are also much more expensive. Numerous dyno tests have proven over and over that there is no better manifold of this type for achieving maximum power and torque while actually using less fuel doing it. Proving again the overall efficiency of the Hurricane.

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.
