The proposed models were a , 5.0 L V8 engined version of the Holden LJ Torana GTR XU-1, the Ford Falcon GTHO Phase IV powered by a 5.8 L V8 engine, and an uprated version of the Chrysler Valiant Charger fitted with a 4.3 L Hemi-6 engine [REF].
While testing the prototype Torana V8 in a Sports Sedan race at Bathurst during the Easter weekend in 1972, Holden Dealer Team (HDT) boss Harry Firth calculated that the car, driven by regular HDT driver Colin Bond, reached on the 2km long Conrod Straight.
