My truck starts great and idles around 700-800 rpm, once you start
driving and then go into neutral or park it will rev up to 1000 rpm.
So when I am in DRIVE, and want to goto reverse - i go into neutral
and it revs so high the CLUNK is louder than i would like it before it
gets to reverse.
In drive and reverse it idles around 700-800 rpm.

Quite possible your choke is sticking on, remove the top of the air
cleaner and see if the butterfly is not completely open. If it is
partially closed, it may be due to a stove, or electric choke coil
that has failed. Or possibly a pull-off is not functioning due to no
vacuum signal or a ruptured diaphragm. Is it an original carb i.e.
Quadrajet? Check and see if your idle stop screw is resting on the
stop when the idle is high, if it is then you could possibly have an
internal fuel leak that is causing a higher speed, this will typically
have some rich condition symptoms. Your carb could just be out of
adjustment, your timing could also be advanced too far.
