In an era when turbocharged four-cylinders routinely crack 300 horsepower and electrification is reshaping what a performance car even means, it’s worth pausing to appreciate what GM pulled off with the LS7 – a naturally aspirated 7.0-liter V8 that answered every question with more displacement. No turbo, no supercharger, no hybrid assist. Just a massive, hand-built American engine doing things the old-fashioned way, and doing them brilliantly. That engine is now gone from production, which makes understanding its story more important than ever.
