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 vacuum fitting in number 6 intake runner thread is 1/4 NPT
The centre fed 2 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 AS0142 for those wanting to run a larger cfm 4V carburettor.
