What is a 'Special Six'?

In Australia, we had a 69 model slant 6 that was in a VF Pacer that had 175hp....wonder if that was it ????
I saw some reference to that (perhaps on theAll par site) and wondered that myself. Is there any way to find out the engine code used for that version?

Edit to add: So you got me going, and I found this reference on the Aussie valiant.org site for 1968 for the VE Valiant: "The 225 slant six continued with 145 bhp (109 kW), but a new 160 hp (120 kW) Super Six version with a two-barrel carburetor, revised camshaft, and upgraded exhaust was now available as well. " This looks to be the same /6 varaint that you mention above for the '69 VF.

Soooo, it's maybe the earliest incarnation of the Super 6; the 1968 year start of this Aussie /6 variant for the VE matches the first year that my old Chilton's has a specific engine code for the 'Special 6' option. And the Valiant.org site lists this for use in the '68 and '69 Aussie cars, which matches the listing that the C engine code was for the same 2 years.
