Generaly if you take 50kw-60kw off the factory number So FG has about 210-220rwkw But every car is different, some have more some have less Auto also has a little less power than manual at the wheels
Driving my mates VY SS... Gee it's bloody slow but with full exhaust, the sound is so bloody good Can't beat boost, but an N/A v8 is a beautiful thing to listen to when cruising around. :-)
I'm sure an engine number check will answer your questions... It would not have come factory with a 270 motor, my guess is a rocker cover change has been done Is the car stock ?
There is nothing in that article that says yes it's coming And the picture of an engine is from a B series When it's on the road or in a showroom I'll believe it's here
