  • Requires addition of starter and fuel pump (not included)
  • Clutch linkage bosses are drilled and tapped
  • When using cast-iron exhaust manifolds, lower head bolts may need to be replaced with bolts with shorter heads for clearance
  • Designed for pre-1976 street vehicles or any off-road vehicle

    The Chevrolet Performance ZZ 427 conjures thoughts of greatness like the legendary Chevy big block 427. It powered some of the most storied cars in high-performance history. The ZZ427 crate engine maintains the good, original characteristics while adding modern touches: updated 4-bolt main cast iron block, forged internal rotating assembly, 10.1:1 compression ratio and aggressive hydraulic roller cam. The engine's top half is the same as the Limited Edition Anniversary 427; the intake is a matching high-flow oval port aluminum piece. With 490 ft/lbs torque and a conservative 480 HP rating, this is still one of the best crate engines for nearly any big block application!
