Yes, yes. The first Torana was the HB, and it was released on May 21, 1967. But that was preceded three years earlier in Australia by the Vauxhall HA Viva by GM-H, the car it directly replaced.

What's more, the hp in the GTS 350 version dropped to 275. GM Holden replaced the Monaro as its primary racer with the LC Torana GTR XU-1 in 1970 and is why the '71 Monaro was so lackluster.
