Manifold Intake: Pontiac V8 326-455March 2022.. this part appears to be discontinued by the maker, enquire for updates if this notice is still here. This is the next step in performance intake manifolds for Pontiac V8 owners wanting standard height attributes so you can still run your factory Carby and keep the shaker or air cleaners at functional levels. This manifold allows the use of the EGR valve as per factory if wanted. Use stock carb on Trans Am for shaker hood clearance.
