I know it says 1999 - 2014+ im sorry, but I couldn't find anywhere else.

I have a 1986 Silverado C-10 swapped from a 305 to a 350. My issue is the truck wont start... It will crank, but wont start, Though when I hold my foot on the gas pedal it does this weird thing. Here I have a video of it (turn volume down!)
Dropbox link - https://dl.dropboxusercontent.com/u/12184626/VID_20130802_132140.mp4

If anyone could help it would be EXTREMELY appreciated!

I would say, from the sound on your vid, that the engine is trying to start; I'm sure you know you need fuel, air and spark to start and run an engine. I think your spark is coming in at the wrong time. The engine needs to be timed.
I suspect when looking for TDC, you mis-took the exhaust stroke for the compression stroke, or, the distributor is 180 deg out.

Exactly what i was thinking!

You did notice that it wants to start once I put my foot down right? And when I FLOOR it, it will "run" at like 200rpm but the second I let go it dies. Oh also, I forgot to mention that the engine was running perfectly fine, until yesterday... thats when this started.

Going from this:

swapped from a 305 to a 350. !

to saying this

I forgot to mention that the engine was running perfectly fine, until yesterday... thats when this started.

is a completely different problem.

Like I said earlier, you need fuel, air and spark. One of them is missing.

My dodge did that. The timing was a little off and the map sensor was bad.

The computer gets its biggest bits of info from the map sensor, and temp sensor

What I meant from that was "it doesn't have the stock 305 in it anymore, so go off of the 350" Sorry for the confusion.
SO I got it running.. recharged the battery (since I killed it) floored it and sat and waited to see if there was an RPM change, there was! It slowly creeped up back to normal! and after I redlined I let go and idled like new. But sadly, the previous problem I had which was the throttle linkage sticking, its doing it again... so its holding my idle in park REALLY high!
