Last year Any Given Reason visited the workshop of well known Adelaide race car builder Garry Kirk to take a closer look at a Dakar car he was preparing for a customer. We noticed another interesting shape sitting under a car cover in the corner which was Garry’s next customer project – a 1972 LJ XU-1 Torana tarmac rally car. Now that the Torana is nearing completion, Garry invited AGR back to take a closer look at it. I’m not usually a big one for the Torana, but this example is a little different.
Anything with that number of Weber carburettors simply has to be a good thing, you just know it. But the thing that makes this engine really special is the custom head, made by J.Zed. It’s essentially a copy of the Duggan and Irving heads from back in the day, and features a down port inlet and redesigned valves and combustion chambers for increased flow. And the results speak for themselves – this engine recently produced 327hp on the engine dyno. When you take into consideration that the stock car makes 200ish on a good day, and that Brocky’s Bathurst winning car never had any more than about 250, that’s a pretty impressive figure. And a final kerb weight of less than 1000kg makes for an entertaining drive.
That power is sent through to a Tex Racing 101 4 speed Nascar straight cut dog box. With a magnesium casing and small size its extremely light, and given that these boxes are designed to take 750+hp of Nascar V8, it should prove almost indestructible in the Torana. A custom bell housing was needed to mate it to the straight 6 motor. Continue reading
