I don't know your year--make--model? You should be able to remove dist cap, crank the engine, watch which way the rotor turns, then you know the direction of rotation. Most chevy rwd v8, firing order, 18436572. The driver side bank is odd numbered, 1357.
The passenger side bank is even numbered, 2468 from front to back. Put your number one piston on tdc of compression stroke. Then whichever spark plug tower the rotor is leading into, should be number one, then you follow the firing order around the cap.

firing order for 5.7 v8 is 1-8-4-3-6-5-7-2 mostly all of the chevy v8s are the same firing order. the rotor button in distributer turns clockwise, the cylinder numbers are 1-3-5-7 on drivers side, 2-4-6-8 is on passengers side. To get started get your distrutor cap[new one] look on the top you will see a #1that's where you begin you must know if if rotates clockwise or counter clockwise start in that direction then follow the firing order and cylinder line up. good-day!! if cap is not marked, just pull out #1 plug, put a straw or similar in plug hole on top of piston. turn engine over by crank in front of vehicle with a wrench, when the piston comes to the very top just before it starts going down. this is tdc. and rotor button should be pointing to #1 wire on dist, cap. follow from there. good-day !!

The firing order is 1-8-4-3-6-5-7-2 Rotor turns clockwise.

This should be the 350 5.7 V-8...as long as it is a V-8 the firing order is the same for Chevy's...18436572...#1 being drivers side front...use to confirm #1 on distributor cap...recommend you change one wire at a time...:) passenger side starts with #2 in front...even #s on passenger side...odd numbers front to back on drivers side...1,3,5,7...passenger side ...2,4,6,8...:)

1-8-4-3-6-5-7-2 The #1 spark plug is the front spark plug on the drivers side and the cylinder location in order from front to back on the drivers side is 1-3-5-7 and on the passenger side it is 2-4-6-8. The ignition rotor rotation is clockwise.

If your Distributor cap is not numbered then replace the new wires, or transfer the old ones to the new distributor cap one wire at a time. Identify the #1 spark plug wire and start from there.

350 Chevy engine in what? 1990 Corvette? Who built it, did you?

Sounds as though you have plug wires wrong.
Firing order is 1-8-4-3-6-5-7-2

Distributor Ignition System:
Distributor rotates Clockwise. (Rotor)
Find Number 1 tower on distributor cap, go Clockwise with Firing Order.

Distributorless Ignition System:
VIEWING the engine from the Front of the car.

Spark plug wire connections along the back, starting from Left side going to Right side;
2-3-7-4

Spark plug wire connection towards the Front of the engine;
6-1-5-8

(To guess I would say you have 5 and 7 wires switched)

Left side cylinder order is 1-3-5-7, going from front to back.
Drivers side is Left side.
Right side cylinder order is 2-4-6-8, going from front to back.

Not sure what you mean by 8-6-4 but this will help you. Pick the correct one for your application:
