This is one of many test-fits of the V8 to the 016 transmission. In order to mate to the gearbox, you have to basically grind off quite a bit of the bottom of the block on the V8. It’s not in a critical area, but it does take a bit of guts as you don;t want to get it wrong. Once enough has been removed, the motor drops over the 4000 subframe and will bolt directly to the 016 gearbox.
Sure, they don’t quite go together yet, but that’s for another post.
With the motor matted to the box, it’s possible to get the height set. I also took the opportunity to replace the shift linkage bushes and plastics which are notorious on these cars for going sloppy.
