your question is not clear do you have a distributor or do you have coil packs ? yes there should be two sets of wires that lead the the side of the dist. usually the back three are from the dist and plug in only one direction. the other two are 1. power and 2. tach output. these plug in to the outside two terminals and are usually labeled. behind the air cleaner is the distributer
The spark plug wires connect in the 7,3,5,1, 8, 6, 4, 2 order on the 350 motor for the Chevrolet Silverado made in 1990. This changes in the models built after 1990.
YES it will fit right in.
inside the distributor.
Reuse your old 305 distributor.

you remove the wires that are going to the distributor and look where the distributor meets the intake there is a little plate the rests against the distributor and it has a bolt in it remove that and pull distributor up and out and u have to remove wires that go to the plugs as well
YES, The 350 Vortec does. It is in the back top side of the engine. All the plug wires go to it.
All V8 Chevrolet engines use the same firing order: 18436572
remove dist.cap.unplug wires and hoses mark rotor where it is pointing...remove holddown bolt remove dist.
driver side 1357 passengerside 2468..
It is inside the distributor under the dist. cap. The wires that you see on the side of the distributor are hooked to the module.
All V8 Chevrolet's are 1,8,4,3,6,5,7,2 with 1,3,5,7 on the left bank and 2,4,6,8 on the right with the distributor rotating clockwise.
