Ford big 6 owners now have a new manifold option when it comes to upgrades on their 240, 300 or 3.9L Ford inline 6 cylinder.
Aussiespeed has used the technology, expertise and knowledge that has been acquired to develop intake manifolds for some of the worlds most popular hot rodded 6 cylinder engines in the all new Big 6 design.
The centre fed 4 barrel design offers a longer runner than other manifolds and a cross sectional port area that will help it perform from just off idle to up in the rev range.
The manifold has a fuel dropout tray cast into the plenum floor as well as provisions for fuel injectors or nitrous oxide on the cylinder head flanges.
There is a 2 barrel version also available part number AS0524 for those wanting to run a 350 or 500 cfm 2V carburettor.
Length from head to carb pad at widest point 287mm
