I have a 1986 Chevy K10 Scottsdale 4x4 with a 305 in it. I have replaced spark plugs, Wires, Rotary Button,distributor Cap Fuel, Pump and filters, Carburetor. But it has no power. It will idle and start up fine but when you put it in gear and push the gas it will barely go. Like no horsepower.

Check your compression you'll need at least 120 psi and within 10 % of the highest reading for the rest of the cylinders. This is a basic check out. It could be quite a number of diffrent things that could cause your power loss. Including a restricted exahust if you've been missfireing for any real length of time.

Make sure you are getting the correct fuel pressure and volume.
