Proper idle RPM

[minifridge1138]

Hey everyone!

Quick question: what is the proper idle RPM for a stock 350 with a carburetor?
Also, is that the RPM for the car being in gear (it's an auto) or in park/neutral?

Since i don't have the cross fire anymore, I don't have to worry about confusing the computer.

Thanks everyone!

I'd try to get 650 in drive with everything being stock. No cam, headers, or any other mods. Be sure and set the brake and block the wheels.

Everything is stock except the headers.
Right now it idles at 750 in drive and just seems way too high.

When I set this, I ask the wife to sit in the car and hold the brake.

Thanks for your help!

Yep, a tad high. Back it down 100 or 150 rpm. Curb idle (Park) will be about 50 rpm higher than with the car in Drive.
