Can anyone tell me how to determine how the cylinders are numbered on a chevy 327 engine?

8 7
6 5
4 3
2 1

front

Put engine at top dead center (using timing marks) then pull dist cap to see where the rotor is pointing thats #1. clockwise its 18436572
drivers front (1) 3 5 7
pass front (2) 4 6 8

Standing in front of the car, cylinders are2-4-6-8 on passenger side, 1-3-5-7 on drivers side.

1357 on the drivers side front to back, 2468 pass side front to back. #1 on the dist is usualy around the 4 or 5 oclock pos looking from the front ot the car. the Dist could have been put in in any position over the years. Best to set it to #1tdc and start from there.
18436572

1 2 buckle my shoe
3 4 shut the door
5 6 get some sticks
7 8 lay them straight
9 10 a big fat hen

all above are right plus this
Left front piston , crank the motor untill piston reaches top , normaly on the harmonic balancer also known as drive pulley
you will see a tab, to make sure piston is top dead center.

once this is done , if the distributer is still in place , remove cap and notice where the rotor is pointing, this is where you’ll start with wire #1. start wiring in same rotation firing order.

once the wires are on turn the dist. back about 3/8 inch to retard the motor .

you’ll also notice on some orginal manifold will have marking , which reads cyl 2 4 5 6

crap…thought i was the first answerer…anyway on the driver’s side it is 1,3,5,7. on the passenger side, it’s 2,4,6,8.

1-8-4-3-6-5-7-2 firing order and #1 isfirst plug on drivers side nearest radiator. drivers side is 1-3-5-7 and passenger side is starting at the front 2-4-6-8
