It's been a long time since i've messed with fiat engines, i've forgotten there markings, but as far as i know this is the copy of the base engine that was fited in the 124 sedan. It started life as a 1200cc chan driven engine, and grow to 1600cc in my niva, and letter to 1700cc in the new niva, which is still in production. The 127/128 engines are different family they are belt driven engines, i know them intimately, they are domestic cars, my country was part of yugoslavia and yugo's 101,128, fico are still driven but most of them are in scrap yards.
