XY GT shaker

Yesterday I mentioned that the engine used the snorkel intake until the throttle was opened. This was the case with the ‘normal’ XY GT.

With the GTHO Phase3’s, things were slightly different.



Ford removed the snorkel and fitted a blanking panel, and let the 780cfm Holley carburettor take its air continuously through the Shaker.

As an aside, note the sticker on the front of the rocker cover reading ‘CK608A1’. This has some significance as it shows that the engine is a U.S. imported Cleveland engine as fitted to XW and XYs. The ‘K608’ signifies that is is a 4V engine - an M-code in U.S. VIN parlance - and ‘A1’ signifies that is is, A - First design level, and 1 - First revision. The ‘C’ prefix is unusual and doesn’t show up anywhere in Ford U.S. literature but is generally accepted to mean export.

To further digress, ‘CK617’ was the engine code for imported Clevelands fitted to XA and XB GTs. Very early on, all XAs, automatic and manual had imported ‘CK617’ engines, but the automatic cars quickly converted to Australian built 2V-style engines. Manual cars through XA were fitted with U.S. 4V engines, and some early manual XB GTs had ‘CK617’ engines also, before all XB GTs used Australian built 2V-style engines.
