no, for the older valiants, the 265 is the engine of choice.
We towed a rally car on an A frame with a valiant ute with a 265. Going to the rally, with just tools in the back, the ute was crap. No traction anywhere. Coming back, with a rally car locating the rear end on the a-frame, that ute would overtake anything!
Then it got a bit older and less cared for. I recall burning 20 litres of oil driving from Sydney to Brisbane. 2 or 3 stops to refill the oil for each fuel stop..
