Buick 350 Stage 1 Intake Manifold

Buick 350 Stage 1 Intake Manifold

The 350 Buick engine has a surprising amount of performance potential, but it has been hampered by the lack of a high-performance intake manifold.  Well say goodbye to lackluster performance, and hello to our Stage 1 aluminum dual plane intake manifold for the '68- '81 Buick 350 Engines!

Since its inception, this Stage 1 manifold has been a perfect complement to street and strip combination's by giving a substantial increase in engine efficiency and economy through its proven dual plane runner design. It maintains excellent low speed and mid-range torque for optimum drivability yet increases top end power as well. For maximum versatility the manifold is machined to accept Quadrajet and other spread bore carburetors, or square bore carburetors such as the Holley, Edelbrock, or Demon.

Manifold Features:

• 15-35 HP increase, based on combination
• Improves Power from 0-6500 RPM
• Reduces engine weight by 40 lbs
• Improves fuel economy
• Use for street or strip
• Better throttle response
• Works with GS Ram-Air Air Cleaners
• Clears hood with all stock air cleaners
• Fits ALL 350 Buick's

 

When bolted on, this manifold will actually increase the air flow by 5% at .300" valve lift and 2.3% at .600" valve lift over the head alone. This lightweight manifold (16 lbs) will give the Buick 350 a 15-35 HP increase, and improve torque and power from 0-6500 RPM all while reducing engine weight by 40 lbs.
