AMC V8's have always been well-liked engines. AMC made a good automobile, and though they may not have enjoyed the mainstream sales and success of the "Big Three" automakers, their cars and engines remain cult classics of sorts today. It's been said that some of America's best engineering talents worked for AMC, and there was always a strong culture of performance within that company.
