Background
The Chevrolet/GMC’s second-generation bus and truck chassis broke cover in 1984. Code-named ‘B6’, it featured six-litre (336ci) and seven-litre (427ci) petrol V8 engines alongside a mighty 8.2-litre (500ci) diesel V8 that also found homes in a wide range of industrial vehicles such as dumper trucks and the like.
The school bus you see here is fitted with that oil-burner, an engine whose design parameters were, as you’d imagine given its original target market, focussed on longevity rather than power. That’s good news for you though, because with careful maintenance they are capable of racking up interstellar mileage, even if the 165bhp it churns out seems woefully low in today’s horsepower-obsessed world. (More on the torque later…)
The chassis was modified in 1985 to enable Ward Body Works to use it as the basis for a school bus, with the shortened bonnet allowing for better visibility and a ‘semi-forward control’ layout, making it utterly fit for purpose in its new role in transporting America’s children around safely.
