Hi All. I'm new to the group and new to Mopar and I'm hoping your wisdom will help with the first of a few issues. I recently bought a 1973 Cuda with a 360 engine and have been having troubles getting it to idle below 1200 rpm. When adjusting lower than 1200, the car stumbles on itself and I need to tap the fuel to get it to smooth out. It has a thermoquad carb, a mystery cam that the owner didn't have the specs on it, but said it was a Cam Dynamics.
I've checked the timing and is set at 14 degrees at idle (1200) and 34 degrees at 3000 rpm. I've checked for vacuum leaks using propane and couldn't find anything around the intake, carb, distributor and brake booster. I'm not sure what to check next, or go back and recheck. I've read a past post where someone needed to recurve their distributor because of idle. Can anyone offer advice on where to go from here?
I'm considering buying the Edelbrock Pro4 Flow EFI system and I'm sure this would fix it, but it's an expensive option.
Any help, advice or guidance would be appreciated.

Welcome to the forum.
Not having an idea of what cam is in it try bumping the timing to 16 at idle and and slow the idle if possible, take it for a short trip, see if it helps the stumble at all. It might like the timing but not the carb ajust.
