Specific details from Aussiespeed about the AS0299 are as follows:

Aussiespeed has extended the Slant 6 4 barrel manifold line up with the new Slant 6 six cylinder short runner manifold the Aussiespeed Sl6 manifold has a runner length including the plenum from the cylinder head flange to the widest point of 30cm. has more advanced features than any slant 6 manifold available.
The AS0299 offers a new tall plenum and can be fitted with any of the Aussiespeed bolt in plenum pigs to change the way and rpm that the manifold performs. By bolting in an Aussiespeed plenum pig you can increase bottom end torque and still get the benefit of a taller plenum in the higher rpm range.
The new molded plenum floor helps to reintroduce any fuel that can drop out at lower rpm from the manifold floor due to fuel drop out.
The manifold has one x 3/8 npt vacuum take off on the rear of the manifold for brake vacuum and auto transmission fitting.
The manifold has nitrous bosses cast into the head flanges & the carburetor can be rotated 180 degrees to run the primaries closest to the inner guard." -Aussiespeed
