Proper RPM at idle when warm

[Six_Shooter]

Hi all,
I have a '66 with a '73 250 in it. I got a new carb installed but the idle seems just a little bit too low.
I was wondering if anyone knew the proper idle RPM for a stock 250. I am searching the internet with little luck so far but will post anything if I find it.
Thanks in advance folks!

The one on the emission decal from whence the engine came. Normally, there are two figures, drive and neutral, and a subsidary value if the air con is on. Google search Maverick forums, these guys generally know, and are helpfull.

Our Aussie 250's used the standard Ford values of
650 rpm +/- 50 rpm in drive
850 rpm +/- 50 rpm in park
