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.
There is a 2 barrel version also available part number AS0142 for those wanting to run a larger cfm 4V carburetor.
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.
