Big Block Dart Cooling

Stepped up meaning two steps richer. The next step would be to change the jets and the rod


As far as running lean it is not. Pulled some plugs today. They are all medium brown in color, not wet. Also, the exhaust tips are medium brown as well. So, I think I'm on the mark in terms of air/fuel. The next step will be the timing. I have a Fire Core Plug N Play and the appropriate coil. Problm I have is I think I punctured the rubber diaphram while I was adjusting the vacuum advance. Not matter what I do in terms of adjustment it surges at light throttle. I unplug the vacuum advance and the surging goes away. I also need to change that T state to 180 as well.

As far as the water pump housing is there a housing on the market that doesn't have flow issues? I did order a Flowcooler pump today. I'll put that on when I change the t state and go with pure distilled water and an additive such as Wetter Water


All these changes will be done one step at a time so I can keep track as to what and doesn't work.
