Ford 400 4x4 Crate Engine by Tuff Dawg Engines

This Ford 400 crate engine by Tuff Dawg Engines was specifically designed for the person that wants to replace that Ford 351M or Ford 400 in their Ford Pickup, Bronco or 4x4 and get the extra power it never had! With the help of CompCam's split-duration cam this Ford 400 is a great engine with strong throttle response and added torque and makes this Ford 400 4x4 Crate Engine by Tuff Dawg Engines the best choice for that added power where torque is the focus without a lopey idle.

The balanced rotating assembly (typically includes crankshaft, pistons, rings, connecting rods, rod bearings, and balancer) featured in this engine:

  • 4.000" stroke nodular iron crank
  • 6.580" rods with ARP rod bolts
