I need to reposition my

Have you removed the distributor? If not , turn the engine by hand to line up the mark on the front balancer with "0" on the timing scale (found on the driver side or top driver side of the timing chain cover, front of engine) If the rotor is pointing to the firewall, make one more turn of the crank. The rotor is now pointing to #1. In reality, even if the distributor is a tooth off. you can use the closest cap tower as #1( place the cap in in position and mark the housing where the #1 tower position on the housing, then remove the cap and set that mark to the rotor position and lock down the adjusting fork), providing there is enough slack in the harness to allow 1" (turning) movement of the distributor in both directions. If not, then you must remove the distributor and re-position it so this is possible.
Using the location you have designated as #1, order is 18436572 clockwise around the cap. Cylinders on driver side are 1357, pass side 2468 front to back. Once its assembled and you have started the engine, use a timing light to fine tune timing (most chevy engines like 8degrees before top dead center, regardless of manufacturer settings)
Good luck!!
