Procedure: 1-Remove Negative Battery Cable. 2-Remove Intake Manifold. 3-Before Removing Ignition Coil(s) Spray Compressed Air Around The Coil Area And Spark Plugs

Back fire out the carb is a sign of timing issues. Either yours is off, or your timing chain jumped a tooth.

If you want 300hp out of your 318 this will get you there: Bowl port the heads and have the valves back-cut 30*, Edelbrock RPM intake(Airgap is more money and the rpm and rpm airgap are basicly the same), Any 600cfm carb, Comp 20-309-4, Headers and dual exhaust. This combo will give you great bottom end and will make 300hp.

The cam, intake and carb alone will not get you there, you need more head flow. So bowl port the heads, or install some 360 heads. good day ! or is this a bit much !!
the 1973 Mopar 318 has 150 hp at 3,600 rpm.

The choke may be out of adjustment if the choke blade is fully closed you may have to adjust until partially open. The other possibility is the distributor is not installed correctly or the plug wire may be mixed up.

Those rattly noises are detonations,  caused by a very lean mixture. All the other symptoms indicate that the fuel flow to the carb is too low. Since you have replaced the pump and the filter, the only other things left to check are the lines and the tank sump. Or you could install a much larger pump.

Have you looked down inside the engine were the dist. goes ? If you do you will see the oil pump drive shaft . You will notice a slot cut in it , now look at the bottom of the dist. shaft . You will see a key or it looks like a standered screw driver . Probably not linning up , need to take a long screw driver an turn the oil pump shaft till they do .

You need a matching manifold or an adapter. Most any auto parts house will have one.

i have a 355 motor and i run autolite copper plugs and they work great, and most plugs are pregapped but just as a refrence 0.35 thousandths is the gap for that

I agree, jumped timing. Check to make sure the dist is tight. Than check for tdc on the #1 cylinder. When the #1 cyl is TDC the rotor should be pointing to that wire on the cap. Take the cap off while checking. Also is easier to turn motor by hand without plugs in motor.
