A 616 engine can be upgraded with angled PCs. There is one single type of PC that fits.
On 60x engines the PCs are special. The glow plug hole is different.
Angled injectors on 616: change PCs and injectors
Angled injectors on 617 turbo: way more complicated. The PC shape is different.
I have a picture of a disassembled PC.

The angled PC that will fit the 616 is expensive and I wanted to come up with a way, short of making a new PC, to have an angled PC for the 617 as well. So I am playing with a 616 PC to see how practical the concept is.
I am basically going to make the upper portion of the stock PC, (where the injector goes), solid and machine an angled bore and new seat.
If I turn down the course threads and cut new treads in the injector housing end, I can get up to 7 degrees of angle. This however requires the use of only these injector bodies. I am wondering what the major diameter of the stock angled injectors is, as that diameter determines the max angle I can get.
I was just wondering what the injector thread diameter and pitch is of the angled injector / PC so I can determine if a standard injector will work. That would allow the use of stock injector bodies, although I think I remember something about the line nut threads being different between the 61X straight and the 60X angled injectors. If that is indeed the case, then I will just modify the stock 61X injector bodies.
