7.0 Liter Engines: Under the 7.0-liter engine size General Motors manufactured the older 427 cubic inch big block engine as well as the newer small block LS7 performance engine. Often referred to as the Chevrolet 427 engine, its big block configuration made it widely popular for performance applications just as the newer small block LS7 has in the last couple decades.
