Default I have a 94 firebird lt1 with some problems

Hey thanks for looking at this post, I could really need some help!
I have a 94 lt1 firebird, it's an automatic, trans am gt style, with some problems.
Over heating:
I've replaced the thermostat, had my radiator checked, got an air dam, but haven't gone to replace the water pump. It's fine when in town but once I start to go farther than 15 miles it's done for. Any thoughts?

Starting:
I replaced the starter but the car continues to click when I try to start it, it eventually will start but idk if I have a bad starter or something.

Fuel pump:
when I put some gas into it, it doesn't immediately get gas to the engine, it likes to flutter some, the gauge inside the car also does not read how much gas I have correctly.

Weird reving:
Ok this problem just started yesterday. When I start the car it's not staying at a steady rpm,it's going up and down, reving the engine then going back down, this worries me the most, why is it doing this, what can I do.

Hey thanks for reading this I really appreciate it!, Ill attach a video of what mods have been done to the car by a previous owner, that may help. But anyways please help me, this is my first car and I'm a high schooler and I love this car, thanks!.

Some people are just NOT very observant.....
There IS a forum for earlier Gen II engines.

OP

IDK WTF that video link is supposed to show...

If you do have a LT1 that has been modified it likely has a aftermarket tune in it. Get scan9495 and see if any codes are present and data log...maybe something will show up

You do need to bleed the air from the cooling system if you opened it by replacing radiator...or it will quickly overheat. LT1 are unique SBC in this regard
