2 Barrel Ford 250 2v Aussiespeed 4 barrel manifold, plenum insert and 2 barrel carb adapter. Ford 250 2V intake has the port size reduced on the lower third of the manifold from the port face back by around 10mm.
The reduced port size helps increase air speed and velocity.
The manifold is reasonably low and performs over a wide power band from mild street engines to high out engines.
The manifold plenum floor has a series of cast circular rings to catch fuel drop out at low RPM and when an AS0084 is added it can really liven up a mild street engine.
The manifold has one x 3/8 npt vacuum take off on the rear of the manifold for brake vacuum and auto transmission fitting.The width from the manifold face to the outside of the carb pad is 20mm
