There are two screws that hold it to the distributor.
The wire sequence on the distributor cap just goes 1 thru 6, clockwise, starting from the number one position (which should be marked either on the cap or distributor).
No need to if the distributor was not moved.
on this old distributor there is a cap that holds the wires in place on the distributor. Is there a trick to remove top cap?
When the # 1 piston is at TDC on the compression stroke, the rotor is pointing to at the # 1 position on the cap. # 1 cylinder is on driver's side, at front of engine.
On a 1999 Chevy 454 engine, the number 1 cylinder is typically located at the front of the engine on the driver’s side. The distributor cap is arranged in a clockwise direction, so the spark plug wire for cylinder 1 should be connected to the terminal at the front of the cap. It's important to confirm this with the engine's firing order, which for the 454 is usually 1-8-4-3-6-5-7-2. Always consult the vehicle's service manual for specific details.
