firebird timing

[81firebirdturbo]

So i have an 81 firebird with a 400 out of a 75 grand prix. I had it running and moving until i played with the firing order and now it doesn't start. I've tried different orders but none seem to work any tips/ideas?? Thanks

SBC 400?

1 8 4 3 6 5 7 2

a pontiac distributor runs counter clockwise, firing order is the same as chevy 18436572

There was a knock so i thought it was misfiring
Where it point one on the distributor?

well best way to do it really is pull the distributor out a little, remove number 1 plug.put your finger in the spark plug hole have someone turn it over till your finger blows out,that's number 1 then drop the distributor back in with it facing number 1 redo the plug wires,fire it up turn the distributor to where the engine is running and starting go.then get the correct timing for your engine and set the timing.

another way is remove the number 1 plug,remove the distributor cap.crank the engine till it pushes your finger out of the hole on number 1. put your plug back in, see were rotor is pointing make that your number 1 and install all the plug wires in order start it up and advance the timing.
