Do you want it in 2D or 3D?
These dimensions are pretty darn close.. 118mm port to port (centerlines), front to back. 66 mm stud spacing at 25 deg. angle. M8 studs. approx. 406.4mm (center to center of port) left to right. 59mm port staggered front to back. email me...

Sorry John. I wasn't planning on giving up the file for the injector blocks. I spent quite a bit of time on the design to simplify the machining and use pico injectors for my EFI conversion. I was simply offering the bolt spacing info. I can offer the bolt spacing drawing in any format that you would like if interested. Email me.
