4.0 sohc blocks

Hi

I just got a 2003 explorer with a broke rod and busted block, I need to know what year blocks will interchange with the 2003. Not flex fuel.

Thanks,
Charlie

Not sure on that one, but iirc 4x4 sohc motors have a balance shaft in the lower crankcase or off to the side, so there might be a difference there.

Probably easier to find an entire motor ain't it?

Balance shaft is there to smooth out the not-as-smooth-as-an-in-line V6.

The 4.0 is a noisy bastid, so they put that balancer band-aid on it to make it a little more palatable.
