Ok, I have a 71, Ford LTD.. I dont know anything about cars, and am
going to my dads this weekend, so if I dont respond, thats why.. but
my car hit 40 mph going uphill.. and I NEVER hit the gas. It goes by
itself, just have to hit the brakes to slow down, even then it tries
to go.. I think it might be idled too high, but any lower.. and it
stalls out. PLEASE help :(

Carb is way out of tune. Idle speed / curb speed solenoid is stuck, or
dashpot, or choke linkage/bellcrank could be too. You need to get to a
mechanic(not a "tech") that KNOWS carbs. It sounds like it's pretty
straight forward, you just need to find the right guy. It's a pretty
simple carb on that engine.

Yep, what Rob said.
I;ll add a little more. A constant high idle on a carbed Ford was usually caused by
the choke tube(s) being broken off at the exhaust manifold. They pulled heat off of
the manifold to open the choke. The choke wouldn't open and it would stay on fast
idle. On a car this old it could also be that someone has adjusted the idle speed
screw up to compensate for many other concerns.
