Engine, Copo 427 Crate Engine, 425 HP.
The COPO 427 for a stock competition 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.
