The two-stroke V8 GM 871 “bird scarer” engine isn’t original – it was taken from an armoured personnel carrier not long returned from the Vietnam War.
The 71 cubic inches per cylinder (9.3 litres) power plant was cranked up from 318 horsepower to 350hp (260kw) via a change of injectors to achieve road train rating, and the box is a 13 speed Roadranger. The Lachlan McCutcheon family spent $100,000 doing up the old B model.via/read more: ownerdriver
