Shelby 427 FE Bare Block

$ 8,269.00

Fully redesigned, the Shelby 427 Alloy FE Block is 45 percent lighter, yet stronger than the factory cast iron version. It retains original factory engine mounting bosses and bell housing bolt pattern, making it a bolt-in replacement for 390/427/428 cast iron FE blocks. The Shelby FE block is fully CNC machined.

The Shelby block offers these premium performance features:

  • Deep lifter valley reinforcing webs combined with thick oil pan rails and main webs maximize block strength.
  • Thick 0.750-inch deck delivers the foundation needed for maximum head gasket sealing and retention.
  • Priority main oiling system. With the oil gallery raised adjacent to the camshaft bore, oil flow is directed to main bearings first, before going to the cam bearing. Crank life is maximized. .
  • Shelby's FE alloy block delivers superior bottom end stability at high rpm.
