Description

Ford big 6 owners now have a new manifold option when it comes to upgrades on there 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. The carburetor flange allows for the SQUAREBORE Holley, Quick Fuel and EFI throttle bodies using the same flange bolt pattern as Squarebore Holley carbs, The dual drilled bolt pattern allows for carbs to be mounted both Forward or sideways facing. Aussiespeed also manufacture a 2 barrel version also available part number AS0524 for those wanting to run a 350 or 500 cfm 2V carburetor.

Length from head to carb pad at widest point 287mm

The AS0142 has been used on not only vehicles for performance it has also been used on many Trucks that haul big loads.

NOTE WE HAVE HAD 1 CUSTOMER WHO HAS FITTED OUR INTAKE WITH EFI HEADERS AND HAS HAD DIFFICULTY GETTING THE EXHAUST TO SEAL. We are developing our own dual cast iron exhaust headers for the big 6. While we have sold alot of these intakes we have not had feedback as to what exhaust manifolds or headers others have used.

Thanks to Levi for the pics supplied of his  successful fit up of a set of 300 Ford EFI headers with a minimum of modifications. As with any after market performance product, take the time to fit it correctly.

a bit of a reshape on one runner made it easier to get a socket on the stud and nut.

A small amount removed from the runner flange achieved a perfect seal on the Aussiespeed 300 intake manifold.

The clamping washer has done the job, take the time and do the fit up right. This is the rear of the engine

Since the pictures above were added we have had many customers fit our Ford 300 manifolds with the EFI headers, they have been run with carburettors and EFI systems like the Holley Sniper.
