I'm with you now, thats the crossover pipe that you have cut and welded the AN fitting to. What did you do with the port that goes from the thermostat housing to the water/vaccum pipe connector? Block it off?
You can't block that off unfortunately, and if you're planning on having heat, that is something you'll need to keep there. However you can modify it to remove the vacuum pass through, but you'll also need that if you're planning on running the vacuum pump with the stock hoses to the brake booster.
Whoops forgot to take more pictures, sorry. Should be around the car again Saturday.
In the meantime we made a video about the car, covering some of the work done on it. A bit different from the rest of the series, but oh well. Hope you don't hate me too much I'm not usually on camera :lol:
