BUICK 400-430-455 INTAKE MANIFOLDS
Our modified Buick intake manifolds incorporate modifications developed on the flow bench and race track.
OEM CAST IRON
| Stock Appearing “SHOOT-OUT” cast iron intake | $475.00* |
These intakes have been proven successful on 11-second street cars. 100% streetable. They incorporate a modified plenum and depending on your application may include a reduced and radiused divider wall. Intake runners are matched to head ports and recontoured to increase airflow capacity. Stock external appearance is maintained. Cast Iron Intakes are degreased, shot blasted and visually inspected before porting work begins. Manifold is primed and painted Buick red, ready to install.
(Note: 1972-1976 intake manifolds are $50.00 more due to additional work required due to air pump passages)
| Stock Appearing “SUPER SHOOT-OUT” cast iron intake | $595.00* |
The SUPER intake also includes the boring of an access hole in the under side of the intake to allow additional porting to increase airflow to cylinder #2 and #3, which also helps to improve runner balance. Stock external appearance is retained. Recommended for maximum effort Stock Appearing engines.
(Note: 1972-1976 intake manifolds are $50.00 more due to additional work required due to air pump passages)
Bob Linquist's 1970 Buick GS uses this intake on his stock appearing 455, that has run 11.81 @ 116MPH on bias-ply street tires!
| Light weight option** | $155.00 |
Intake manifold weight can be reduced by 4 to 6 pounds by machining off the exhaust crossover from the underside of the intake. The exhaust crossover passages MUST be securely blocked in the heads to prevent exhaust gases from entering the crankcase. This option is for the serious Stock Appearing racer that is looking for every possible edge.
