HP, its a standard GT. However being the end of the XW build (Sept 1970), it copped some excellent items out of the factory, including the Electric Blue paint, 31 Splines, Nodular Iron, Front spoiler, and some model change over parts such as XY radio and rear view mirrors.
The engine has been tickled up to 210rwkw and 820nm of torque out of the original block, which puts it just above PhaseIII kw's and enough torque to make the manual an auto if your feeling lazy.
Chevs may go, but theres nothing like a HO!
