WOW was the reaction we got in 2009 when we sent the Aussiespeed AS0024 to a few engine shops to try, this total new style and design of manifold gave great increases to the “225 tower of power”. With a few revisions in 2016 it was kinda like a 7 year itch the AS0024-16 has under gone a few changes cosmetically, It will now accept carbs mounted in both North South & East West.The manifold has one x 3/8 npt vacuum take off on the rear of the manifold for brake vacuum and auto transmission fitting. Some mods may be required to mount your carb in the sideways position. Carb linkages may foul the intake manifold, We suggest you check before bolting it up incase any metal needs to be removed.
