i have the 2.0 8v dohc in my sierra which is dying . i have found a 94 transit at my local scrapyard with the dohc . was wanting to know what the difference is regarding the cams and comp ratio and would it drop straight in .

 

can i suggest if you get no joy here, try the fordsierraownersclub forums, they were great help when i had twin-cam problems a few years.
