I could then install them into the block. Luckily the original Ford dowels just tapped out with no fuss.
1st attempt didnt go well and I figured out that Id put the dowels in 180deg out!!
2nd attempt looked better with the measurements getting closer to spec.
3rd got closer still.
Finally on the 4th attempt we hit the jackpot and all the measurements fell into spec with a total missaligment of 0.0025"
It might appear like this was a quick and easy process but it wasnt! Each time an adjustment was made the bell had to be torqued up to spec and remeasured. If you take into account the couple of times I knocked the DTI out of position and had to set it all up again and remeasure to confirm correct setting it took about 5 hours in total to get to here. Still, its worth it!
So thats it bell housing correctly aligned to the crank centreline and flywheel face.
Clutch assembly next!
