If the starter solenoid is clicking, it's at least getting (some) power. Is it clicking once, or chattering? Check the battery voltage using a multimeter. Have you cleaned or replaced the negative battery cable yet? Where does your negative battery cable run? What is the condition of the starter cable? There are some other things to check after you check these.
You sound new to trucks, so let me clear this up early: just because something is brand new does not mean you should eliminate it from diagnostics. Assume you know nothing about the condition of the parts and check everything step by step. In other words, if someone tells you to check something, don't ignore the advice by saying the part in question is brand new.
Wrong.

You stated that you poured oil into the cylinders? Did you install the plugs back in? If the engine did actually turn over and a cylinder is full of oil, then you may just have a hydraulic locked situation. If you did this in the exact order that I read them, then this is likely the case. Remove the spark plugs and attempt to turn thr engine over again.
If the engine turned over slightly, then it will move and it is not "locked up" so you should be able to get it to turn.

oil i poured MMO after it stoped turnin over. All plugs are removed. Yes i started at the battery and worked down.
Battery is 800cca battery brand new.
The solenoid Clicks over but nothing more sounds or anything happen.
so we pulled the starter thinking that was the problem.
Starter tested out great.
My brother said that the + wire was getting really hot and a lil smoke was coming off it when we turned the key.
Reinstalled the starter
Fixing the gorund cable with brand new 2 gauge wire.

If the positive battery cable was smoking, too much current is passing through it; and if this starter otherwise checks out fine then it's likely having to work too hard to turn the motor over. It sounds like the motor is locked up; refer to 75F350's post to verify.

Absolutely NO reason to use anything but 87 octane. Higher octane is just harder to light and produces less energy when burned.
As for your issue.........try another battery. It may have a dead cell, etc.
Hard to believe the motor would LOCK UP in just a year. Mine sat for years and years and runs mint.
Possible the previous owner toasted it and is not telling you something.
cheers

Gasoline will ignite on its own given enough compression. The higher the octane rating, the more it can be compressed before it ignites without a spark. If a motor runs fine on 87 octane (as is the case with many stock, relatively low-compression motors), then increasing the amount of octane does nothing except waste money. Higher octane fuel is for higher compression engines.
