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. TA Performance Products solved the problem when we introduced our very first product in 1983... the Stage One, aluminum dual plane intake manifold for the '68- '81 Buick 350 Engines.
Since it's inception, the TA Stage 1 manifold has been a perfect compliment to street and strip combination's by giving a substantial increase in engine efficiency and economy through it's proven dual plane runner design. The TA manifold maintains excellent low speed and mid-range torque for optimum drivebility, 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. 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 light weight 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.
