We currently have a Cosworth YAC/YBM Jennings Motor available for purchase.

This motor was disassembled during a scheduled refresh. The owner decided to replace the motor with a Duratec during the refreshing, so it remains unassembled. The engine includes all photographed parts (see gallery below).

Specifications:

  • 12 bolt crankshaft
  • TDC dry sump pump
  • Cast aluminum oil pan
  • Weber intake manifold
  • Cosworth pistons
