Super Six install on 1974 Dart

Got it running! Idle was pretty rough at first, but with my AFR gauge it was very easy to see that it was on the rich side. Of course I probably could have also looked at the black spot forming on the driveway under the tailpipe. :-)

The first time I stepped on the gas pedal, the car jumped so fast I almost drove off the driveway into the grass. What a difference! One thing that makes it feel livelier is the throttle return spring is a good bit lighter than what I was used to, but the engine is definitely making more torque now as well.

It still pings in high-load situations (vacuum below about 5 inches, RPM above about 2500), and the AFR shows lean in those conditions (16-17 going uphill on the highway), so that problem isn't solved. But the Super Six is definitely a major improvement over the 1945. Now I just need to dig into the BBD adjustments to figure out how to enrich the mixture at speed.

Other issues:
- The choke heater doesn't seem to be connecting to the terminal that powers it. The connector is very loose and the choke seems to stay closed longer than it needs to.
- The throttle cable is about 6" too long at 24" end to end. Thanks to FABO user RPMagoo for agreeing to sell me an 18.5" cable for a reasonable price.
- The air cleaner touches the underhood insulation. I might need to shorten that choke control rod after all, so I can use a thinner carburetor gasket. Right now I have a 9/32" gasket, plus two thin gaskets that came with the carb.
- The heated air inlet door (in the air cleaner horn) didn't seem to be closing, even though I think it should if the ambient temperature is under 100 degrees. Need to troubleshoot that.
