David Z old motor was sold and replaced with a duratech motor 2.5 liter...it happend about a month ago, becaus ei was planning on buying the 3 liter block from Jjennings.
Also the duratecs have timing chains not belts!!!!!!
The only thing that the belst would affect is the water pump, power steering, alternatior and A/C units.
Now If he replaced the 3 liter with the Zetec, i would like to see that, because that would be a pain to get the mounts in there.
