Typhoon Small Block CHEV Dual-Plane Intake Manifold, non-EGR, HI PERF Street

The Typhoon is one of our most popular high performance street manifolds. For most street applications we recommend a 600-700 CFM vacuum secondary carburettor. For high performance street use and bracket racing use a 700-800 CFM double pumper carburettor. This manifold produces outstanding power and is .70 inch taller than our low profile Cyclone. It has a provision to machine for a front oil fill tube. No provision for exhaust heated or stock style chokes. This manifold will not fit under a stock Corvette hood.

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.
