    The high-revving horsepower of the COPO racing engines is enabled by the high-flow LS7 CNC cylinder head, which features a 12-degree valve angle for efficient airflow at high rpm. The head is fully CNC machined and the 356-T6 aluminum casting features 275cc (nominal) intake ports, 90cc exhaust ports and 70cc combustion chambers. There's also a thick, 5/8'' deck for exceptional (nominal) strength.


    Manufacturer's Part Number:

    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.
