Expected idle with a Purple Cam

I'm not looking to start a word war over which cam is the best to use. I know Lunati and Comp make great cams for modern builds. But I'm stuck with what I got for now - I can't afford to drop another $400 into my car for a new cam.

I'm restoring 70 340 Duster. No plans for the strip, I just want a fun street car. I want my wife and friends to drive it also so it's important she have street manners. I bought the car 18 months ago and have not driven it but maybe 100 feet. But I couldn't get it to idle respectively for sure. She would stall at anything below 1400 RPM which I doubt is right.

Since then I have rebuilt the carb, drained the gas tank (gas might been 8-9 months old), fixed a half-dozen engine wiring problems (possible shorts), replaced spark plug wires (a couple were shorting out to the exhaust) and I installed an HEI module and coil. I have not started it since because I still have a few more tasks to complete.

So here's my simple question: I looking for an educated guess - something for me to aim for. Assuming I can tune the carb and set the timing halfway respectably, what could I expect to get the idle speed down to? Here is what I have:

340 bored 0.040 over
10.5 compression
MP 284/484 cam
4-speed
Eddy 1406 600 CFM
Eddy Performer RPM intake
Hooker long tube headers
