Chevrolet L83
The Chevrolet small-block V8 family of engines has been around since 1955. It is still a relevant powerplant used in numerous GM models. Of course, during the 1970s and ’80s, it was affected by tightening emissions regulations. The 5.7-liter produced terrible figures and not-so-convincing performance (via Old Car Memories).
In 1984, Chevrolet was proud to show a brand new advanced Corvette C4. It was all-new apart from the engine, which was an anemic 5.7-liter V8 strangled by emissions regulations and delivering just 200 HP. Yes, it was amongst the fastest sports cars on the road in the mid-’80s, but its power is ridiculous nowadays.
