Chronicles of the Blue Goose!

The 300rpm drop from park to drive is no doubt the torque converter. The instability with the idle once in drive is due to an issue with Edelbrock carbs where they don't like fuel pressure above the 4.5-5.5 psi range.

Today I rebuilt and cleaned the carb with no luck. The idle screws weren't doing a damn thing and it wasn't idling like a well-adjusted machine. So I played a hunch after reading about the fuel pressure issue and bought a cheapie Spectre fuel pressure regulator, slapped it on and set it to 4.5 psi. Problem solved! It now stays a steady idle and I can actually tune the carb with a vacuum gauge now.

Next month I'll probably spring for a decent regulator.
