Holden 6 cylinder 12 port 2850 and 3.3 litre engine inlet manifold to suit Weber ADM Ford Falcon 2 stage twin barrel Weber carburettor. It will also accept DGV and other Weber carbs sharing the same bolt pattern.
The Weber conversion is not as popular as it once was is still done by some modified engine owners. The AS0169DP is a dual pattern 2 barrel performance inlet manifold that fits Holden 12 port cylinder heads but our testing has found the manifold performs better as common runner rather than using a divided inlet port runner like the factory Varijet manifold.
The AS0169DP Aussiespeed® manifold is drilled to suit both Holley 350 and 500 2 barrel carburettors and Ford Crossflow 2 barrel ADM weber.
When fitting the Weber carb some additional grinding may be required to the carb pad or carburettor base.
The manifold has one x 1/4 NPT vacuum take off on the rear of the manifold for brake vacuum and auto transmission fitting.
