Need help diagnosing my 76
So I'm having troubles with my 76' F150. I'm a long time lover of Fords I've owned many different ones. But this is my first time with a 460..
Ive only owned the truck for 6 months. I was driving back from the Dump when the Engine coughed and sputtered then ran fine for a few minutes until the next stop, it stalled and wouldn't restart.
so the Battery was dead. Replaced it. I'm noticing the choke plate isn't opening. I'm checking the sparkplugs and wires today. I would greatly appreciate any help.
thank you all.

Let's start out on the "cheap" before throwing parts at it:
Sounds like the engine got a gulp of water, digested it and then got a big slug of water. If it is a dump run truck, when were the fuel filters changed ? Do you run "HEET" fuel additive in the fuel tank ?
Are you in a high moisture environment ?
Battery:
How old was it ? did you replace with new equal to OEM ? Does it sit for long periods without running ?
Being a lover of old Fords is great.. How are your mechanical skills ? Do you have a shop / hand tools / diagnostic equipment ?
Spray that choke assembly down with PB Blaster or equal while you are diagnosing.
Get back to us.

Is it cold there where you are? If really cold, an electric choke will close up pretty quick in the absence of fire.

Sounds like alternator is not charging. Choke is electric so no voltage, no choke opening....
Start with the basics. Check that your alternator belt is tight and not slipping (try turning the alternator pulley by hand, if you can turn it, belt is too loose.
If belt is tight, time for new alternator and / or regulator provided that battery is servicable and there are no wiring issues.

Sounds like maybe a inline fuel filter got clogged up? Do you have any inline fuel filters on it? Are you SURE you have gas in it? Was the battery dead when you tried to restart it initially right after it 1st died? Or from you trying to restart it? Do you have a alt gauge or warning light? Did you have any indication on either?
Either fuel filter is clogged, you ran out of gas, alternator/voltage regulator quit (died) and the truck ran as far as it could on the battery charge. Or maybe the fuel pump died. Or could of been the ignition module died.
I would take the alternator off and take it to a parts house and get it op checked. I would put the old battery on a slow trickle charger and see if you can bring it back to life. Check fuel level, (add 5 gal) and check/replace any inline fuel filters. Then try to turn it over on the old battery and see if the mech fuel pump is at least pumping fuel up to the carb. Crack the line at the carb connection and see if it squirts/leaks out some gas when you turn it over.
Is the choke a choke stove hard line or a elec one?
