COPO 396/390 Long Block
- Replacement long-block engine for factory COPO 396/375
COPO ENGINE COMPONENTS
The factory-engineered COPO Camaro racing engines deliver the power to win, and Chevrolet Performance is proud to offer many of the same components that go into hand-assembled engines for the production cars and our very own COPO 427 (7.0L) and 327 (5.3L) crate engines. Use them to build your own high-performance engine for the street or strip, starting with our lightweight LS7 cylinder block – the same used in the COPO 427 engine – or the durable and economical LSX Bowtie block.
