After many requests about a 2 barrel Chevy manifold we have gone a step further with our AS0044, Aussiespeed Chevrolet in line 6 cylinder 4 barrel intake manifold fits 250 and 292 cubic inch engines offers high velocity ports, divided centre plenum port allowing for a closer flow to all runners.
The Aussiespeed Chev 6 inline manifold is available in to suit squarebore holley 4 barrel carbs the manifold is supplied to accept either forward facing or sideways mounting carburettors.
The Dual bolt pattern accepts squarebore Holley Carburettors from 390 to 850 in both forwards and sideways mounting. The plenum floor is designed to catch fuel drop and re introduce it as air speed increases, It is supplied with an adapter plate to run 2 barrel carburettors
The AS0044 is drilled to accept squarebore carbs in either sideways or forward facing. This also allows the AS0574 to be mounted in either direction. Some grinding may be required when fitting some carbs or throttle body fuel injection for butterfly or linkage clearance.The taller plenum we have found offers optimum performance across a wide rev range. The plenum can be machined lower for hood clearance. The manifold has one 3/8 NPT vacuum fitting take off drilled in the rear of the manifold for brake booster or auto transmission take off.
