7.0 | 7.4L Engine

One of the most legendary engines in muscle car history is the Chevy 454 Big-Block. With the LSX Bowtie block, GM Performance Parts engineers were able to build a 21st century 454 with the latest technology – and it requires no more space under the hood than a production LS engine. It’s perfect as the power plant for a late-model Camaro drag car or a high-tech retro-fit for a ’70 Chevelle pro-touring machine.
