Like an idiot I pulled the distributor on my 1997 chevy 454 without removing the cap to note the rotor position first. What is the best what to make sure i get the distributor back in the correct position?
Pull the spark plug from the number 1 cyclinder, have some tap the key to make the engine jump just a quick tap, hold a long straw down in the sparkplug hole (dont drop it) you should feel the straw move on each tap of the key. you will feel the piston come the whole way up and start to go down, you need to try to catch it when its up the whole way. if you do then take off the distributor cap trace the sparkplug wire that was hooked to the number 1 plug line the rotor up with that wire on the cap slide the distributer back in and slowly line rotor and cap back up again to number 1. tdc put plug back in hook anything back up (cap) should start then. dont forget to tighten distributer bolt before u start it. if it dont start go throw steps again. hope this helps.

Most chevy 5.3 do not use a cap and rotor. Most have single coil per spark plug and wire. Trace spark plug wires to coil usually above the valve cover.

I have had good luck with Echlin caps and rotors that are from NAPA.
You are going to need to mark your spark plug wires so you can get them back on the new cap in the right place. Tape with numbers on it or what ever you can come up with. There should be 4 screws around the lower part of the cap. Take your screwdriver and push down on the screw and turn like a quarter turn counter clockwise and you will see it release from the distributor. If you look at the new cap you will be able to see how it works. Once you have the cap off you will have to transfer the coil to the new cap. There should be 2 small screws on the top of the cap that hold the cover over the coil.
I think there are 4 screws holding the coil in to the cap and you will have to pull the wires and terminals out of the cap as you are removing the coil. Be careful when you retighten the screws in new cap.
When you replace the rotor you will see by looking at the bottom of it that it can only fit one way and lock on to distributor.
Just take your time. If you have any problems I will try to help.

Gently pry the rotor off by putting screwdiver between the rotor and the pick-up coil.
