AUD $690.00


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 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.

The carburettor flange suits Holley 350 and Holley 500 and other 2 barrel carbs and EFI throttle bodies using the same as the Holley 2 barrel bolt pattern. There is a 4 barrel version also available part number AS0142 for those wanting to run a larger cfm 4V carburetor that is the same bolt pattern as Holley, Quick Fuel squarebore and EFI throttle bodies running the same bolt pattern as a Holley square bore.

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.

Below are pics supplied from a customer who successfully fitted 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

Dual EFI 300 headers fitted to an Aussiespeed big 6 manifold, access to bolts is good on the underside.

Many customers have since fitted the EFI headers along with both carburettors and EFI throttle body fuel injection like the Holley Sniper.
