E-Force Intake Manifold Chevy SBC 283 327 350 Fits Stock Heads 82025 Polished

E-Force Intake Manifold Chevy SBC 283 327 350 Fits Stock Heads 82025 Polished and not plated. 

This E-Force Series 3 is a special version of the 82021. While it is the exact same height, it features an open area under the plenum chamber. This provides for a flow of cooling air which keeps the temperature of the air/fuel charge lower thus producing more power and torque. The interior plenum and port design are identical to the 82021 and will provide somewhat better overall power than the 82021 due to the special air gap style design.
