I don’t think it is Australian HFV6 as in LFX, is LGX and massively different.This is a GM HFV6, same as the SIDI in the VF. That was only 210/350.
So how did the new donk get the extra herbs?
I got told on one model cant remember which one it was that the Holden had slightly less power because it was tuned to develop torque lower in the rev range then the U.S. one to suit our driving style here.We have always had lower power levels in the GM engines in Australia. LFX in Camaro 245kw, 210 (91 RON) in Commodore. I believe it's to do with emission control systems.
