If automatic, look for vacuum hose damage/leaks or loose wires that may have come off during the work you did. Is the distributor a vacuum advance and are timing/ points set correctly?

backfiring is ignition of the fuel mixture while an inlet valve is still open. Check firing order as there may be a HT lead crossed . If it backfires then the mixture is burnt in the inlet manifold so there is nothing left for the cylinders so it will stall. If you are running holley carby then check the power valve for a hole in the diaphram Check for vacuum leaks. check ignition timing is correct and not too far advanced. if the HT leads are touching each other this will induce a spark in the wrong cylinder --use lead spacers from an auto spares shop
Plugs and wires are a good start, if they haven't been replaced for a while. I would change the fuel filter and check the air filter. The fuel filter is often overlooked. The ones I change, you wouldn't believe the dirt that's in them.
It sounds like he has the spark plug wires in the wrong firing order. Those are the "hoses" you see on the distributor cap. He changed the rotor $7 part. The timing won't make it shake. It can be off 10 degrees from specification an still run ok. Is it a 6 cylinder or V8?
I'm pretty sure he has 2 spark plug wires out of order. He needs to look up firing order of engine.
When he transferred wires from the distributor cap or put them back on after the plug change, he must have put 2 in different places.
Only other possibility is he cracked a spark plug installing them, it happens.
change old oil and filter make sure all spark plug wires are there and look ok take spark plug out and pour little amounts of marvel mystery oil down into cyl. then turn engine over acouple times if it has a oil pressure guage make sure with spark plugs out and engine turning that you have some oil pressure.then take some fuel line and connect it to the fuel pump on the side of the engine you most take off line going to the fuel tank in order to do this then put all but one spark plug back in the put all the wires on then the one plug that you left out check for spark by installing the wire on the plug and setting the plug on something metal on the car (grounded) the turn the engine over and look if the plug is making a spark if so put it all back together. then with that line you put on the fuel pump stick it into a gas can with plenty of fuel then pour a tiny amont into the carb and try to start
Make sure you were given the right plugs for the car (correct heat range) also check the choke plate after the car warms up to ensure the choke plate is all the way open.
