Hi all,
After a long time and many upgrades, I have final got to take my '66 Charger for a long and highway shake down.
After many anxious miles on the freeway with the temp gauge about 1/8" from too hot, I pulled off, ready to burn my finger tips opening the hood. But nothing. It was not hot. I think the temp sender has been the wrong one from day one or I put the wrong one in there. What is the proper temp sender for a 440 with factory temp gauge? My wiring connector is the slip over thread type.
Next, the idle speed screw is in too far and it's too far off the idle circuit - I'm getting vacuum on the ported hookup. If I back it out, the idle drop way too low, and dies. The mixture screw have some effect so I think the idle circuit is working. Timing is by ear where is runs the fastest and smoothest. It's a '78 440, AVS2 800, Edelbrock heads and intake. I think this was not a problem before new heads and intake. The EGR port is connected to a valve cover breather, no PCV. The brake port (back of carb) is blocked, the brake booster is connected to the manifold.
Finally, I just learned that 440 cast cranks are externally balanced. In the freeway, the car has a rhythmic drone that rises and falls. The faster I driver the faster the drone rises and falls. If I let off the gas, the drone stops. I have the drive shaft rebuilt and balanced. Does this sound like an unbalanced engine? I think my crank damper is from the original 361 engine and maybe not from the '78 440. See picture.
Thanks.
