Played with it a little more to-day. Fun-Fun.
I mocked the timing case back onto it, with the cam and crank in place and a VE pump installed, the gear lash was okay and can be adjusted looser or tighter by moving the case around, then locking the case bolts down.
I must say that this is not going to be hard to do at all!
The one thing I was MOST concerned with, getting the lower dowel pin located so the case will "never" move under load, was concerning me a bit, then I looked at the case closer.
Turns out that the part of the case where the lower dowel pin is located, can either be drilled clear through, or cut open, to transfer punch the center for the dowel pin's hole.
Wouldn't you know I have JUST the junk timing case that will work for this exercise!
Basically, this timing case will become the template for both dowel pins and all of the remaining holes (@ 6 of them).
I also figured out the oil pan, just need to lop off the front of both, the 6.7 one, and an old pre-commonrail one and swap them around, which will probably be the hardest part of the whole conversion.
Mark.
