A facelift of all models provided the LJ Torana which took Holden through to September 1974. A new larger Torana replaced the smaller LC/LJ Models, titled the LH Torana, the Torana was now offered in L4, L6 and V8 Models. Eight different engine options with some new models too. All LH Toranas were 4-door sedans, and came out in 'S', 'SL', 'SL/R', 'SL/R 5000' (this had the largest V8 - Five Litres) and the Bathurst-winning L34 with the hot Five Litre V8 and HQ brakes.
The LH Model was replaced in 1976 with the LX Torana, Holden kept almost all models but killed off the L34 and replaced it with the A9X which was availible in the 4-door sedan and all new 2-door Hatchback. The Hatchback was availible in 'S', 'SL' and 'SS' models along with the A9X
The last LX rolled out of the factory in 1978 when it was replaced by the dreaded UC Torana. UC Toranas were given a modern facelift and availible in only non-sporty models. They were all 4cyl and 6cyl Toranas with unbelievable handling for their time and they were good looking beasts, but VERY conservative in Torana terms. Shitloads of UCs were sold, more than any other Torana, in 'SL', 'SL/E' (which is a luxury model) and 'SL/T' models, SL/T was a Turbo 202 Holden Six which went faster than even the Bathurst Winning A9Xs, they are rare as hell and most of them are just normal SL/Es now because the Strata 2 Turbo kits have been stuck on earlier Toranas or H-series Holdens.
The GM-H Torana was one of the greatest cars ever built in Australia and the first to offer 4cyls, 6cyls and V8s in one model of vehicle.
"Fo shizzle homeboy, my rockin Torana which is teh pwnz0r will kill it"
*The Ford dies*
The prefix of the model numbers are "L" eg. LH, LX, LJ, LC... etc...
This refers to the "light" nature of the car.
The V8 versions, especially the SLR of the 1970s, are sought after by collectors and enthusiasts.
Holden is considering resurrecting the name for a new model.
