Typhoon Manifolds for SB Chevy

The Typhoon is one of our most popular high-performance street manifolds. For most street applications we recommend a 600 to 700 CFM vacuum secondary carburetor. For high-performance street use and bracket, racing uses a 700-800 CFM double pumper carburetor. This manifold produces outstanding power and is .70" taller than our low profile 52000/52001 Cyclone. It has a provision to machine for a front oil fill tube for the original early style look. No provision for exhaust heated or stock-style chokes. This manifold will not fit under a stock Corvette hood. Includes nitrous bosses.
