COPO 427 - 425 hp
The COPO 427 uses the large-bore cylinder block and high-flow
cylinder heads of the LS7 engine and complements them with
a high-compression rotating assembly to deliver big power from
its large displacement. Its lightweight aluminum block and
heads revive the spirit of the original ZL1 all-aluminum 427
Big-Block that helped forge the COPO legacy in 1969.
