That’s the ZIL-130. It was some of the most common trucks in the USSR. Over 3.5 million of them were made. All of them had a 6.0L V8 engine. The Soviets did have V8s, but they only used them in trucks, buses and military vehicles
It's a shame they never made a Soviet muscle car with that engine in the late 60s. It would be fun to have a Soviet counterpart to American pony cars like the Mustang, the Camaro and the Barracuda
