Unfortunately I'm old enough to remember when those rigs were King Of the road. SAR KW are rare in NZ only a few collecters have them now and the DCF 400 International was the mainstay of big rigs in the early 70s on NZ roads. I'm guessing that both those trucks had 71 Detroits in them, the DCF would have the 8V71 and the SAR probably a 6V92 they came with CATs and CUMMINS as well. Back then 350HP was BIG grunt now 600hp is the norm and the EURO trucks are up to 750/780HP. My Dad who turned 90 last month was a Logging Contractor most of his life (he only stopped working 3 yrs ago) and I used to ride around in the truck all day every Day during school holidays from the early 60s, when I was at Highschool I worked in the bush for him, he had a Felling Crew as well as a small sawmill. Great days. Now you can't take kids in trucks and I believe this is a big reason for the worldwide driver shortage, that and the fact you can't get a 19yr old to get out of bed at 3am and work 15hrs a day but that talk is for another time. Love the old photos more of them please and lets see where this thread can go. Cheers Leon
