I am ready to start building the headers for the B1 engine.
The power plant is in the car, sitting on the engine mounts (midplate and front plate).
That B1 head drain line on the rear passenger side is a snug fit between the firewall and the midplate.
And the other side is just as tight between the head and the midplate. But they are done, and I was able to route them inside the chassis frame tubes. So the engine drops right in with the lines installed.
