The Vega wasn't as bad as you think it was.
Ed Cole (the mastermind behind the design and development of the small-block Chevy V-8) was the chief engineer of the Vega project. Reynolds Aluminum developed the A-390 alloy of silicon impregnated metal for the engine blocks. Cole was given 24 weeks to design, develop and place into production a new car....from scratch. Most people don't know, but the Vega was being engineered as the first production models were coming off of the production line. Car & Driver and Motor Trend both voted the Vega "Car of the Year" in 1971. And, problems aside, the Vega easily out performed and out did almost every competitor in their price range. But, because it was rushed into production, many things were overlooked, and later came back to haunt the car. Almost everything about the car was innovative, from the way they were transported to the speed they were built. Once the Vega ceased production, GM sold the A-390 patent to Porsche Ag. in Germany, for $6 million dollars. Porsche still uses the casting techniques and the alloy of aluminum to this day. The oil pump first fitted to the 2.3 Vega engine is the same identical pump on all Chevy LS series engines. The list goes on. A lot of guys still believe the Vega's aluminum block and cylinder bores were the reason for it's faults. It wasn't. After the Vega blocks started appearing with tool steel cylinder sleeves pressed into the blocks, the problems still existed. The real culprit was the Vega's valve guide seals.
