Super Six install on 1974 Dart
After getting everything home, the next step was to take lots of pictures and apply PB Blaster liberally while waiting to have time to tear it all apart. I'll spare you all the pictures of rusty linkages, etc.
I decided to separate the manifolds so I can use my original exhaust with the Super Six intake. That way I know I have working manifold heat, plus I'd like to reuse my clean, graphite-painted manifold that I already worked hard on. I expected to have a hard time removing the two long 5/16" bolts that hold the manifolds together, but those actually came out without too much trouble. I did spray PB every day for a week before I tried loosening them, which probably helped a lot. In the end I just put a wrench on one and tapped the wrench with a hammer until it turned. Then I did the same with the other. Here they are before coming out.
The only problem was there was a second pair of bolts that went into the same threads from the bottom. I'm not sure what they are for. One came out clean but the other's head broke off, leaving the threads in the manifold. Fortunately I don't have to solve that problem if I'm not using the manifold.
Surprisingly the nut on top of the intake manifold, that goes onto the 3/8" stud from the exhaust, was barely even wrench-tight.
