Aussiespeed dual 4 barrel manifold to suit Holden 9 port red motor cylinder heads.
Aussiespeed twin 4 barrel manifold uses our supercharger manifold to suit Holden 186 and 202 engines. The manifold is fitted with a manifold support rod that fits to the engine mount.
A single hole to fit a 10mm socket head cap screw will need to be drilled to fit the manifold support.
For a cleaner look the mounting pads for the 192 blower shop supercharger can be machined off.
Feedback from customers who have fitted both Holley and Quick Fuel carbs have used 390, 450 and 465 CFM carburetors with vacuum secondaries.
Carbs with single metering blocks can be mounted as pictured above. Duel mettering block carbs will need to be mounted sideways.
