The C Series manifolds are designed to fill the void between
absolute street performance and modified street / race applications. These manifolds have been designed to accept
larger carbs of a performance variety because the plenum and runners of the
manifold have been opened up to carry the high volume flow required by modified
engines at high RPM’s.
These manifolds come with stock emissions provisions for
those vehicles which might be used as a modified street / race
application. Vehicles used in race only
may block-off these provisions as necessary.
The C Series Offy open plenum design really boosts engine
breathing characteristics and greatly improves the torque in mid to higher RPM’s. The torque range of these manifolds has been
designed to fit into street modified and competition RPM requirements of the 6
cylinder engines. Depending on the size
of the carb and engine type, the C series manifold has a fantastic range from
approximately 2500 RPM delivery great performance through 7000+ RPM. Naturally, the larger the carb, the higher
the RPM range will be.
This installation adds more horsepower to your 6-cylinder
than any other single piece of performance equipment.
Uses standard 4bbl carb from 400 CFM to 600 CFM depending on whether it’s for street or competition.
Works great with the Edelbrock 1403 500cfm carburetor!
