take out number 1 spark plug and put your finger as to block the hole ,have a friend bump the starter till you feel air rush out real fast / called the compression stroke when it does stop and look down the top center for timing marks on the pulley and line them up on the timing cover then place the distributor in place as so the rotor is pointing at the #1 piston location, basically the dr. front corner and start there, timing order is 1..8..4..3..6..5..7..2.. now if you get all these in right 1..3..5..7 are on the drivers side front to back and 2..4..6..8 on the passengers bank front to back and the distributor turns clockwise .good luck hope this helps you.

Firing order is 1-6-5-4-3-2 cyls. # 1-3-5 on drivers side front to back and cyls. # 2-4-6 passenger side front to back.

SOURCE: 1990 chevy 350 distributor wiring diagram and firing order

The firing order is 1-8-4-3-6-5-7-2.
The distributor rotates in a clockwise direction. The engine must be on the compression stroke on the #1 cylinder. Line up the timing marks. Remove the cap and the rotor should be pointing to approximately the 5 o'clock position.

Good Luck

SOURCE: how do I put a distributor in a 1989 chevy 350

Remove the valve cover on the driver's side and turn the engine over by hand until you see the intake open on #1 cylinder. and then close followed by the exhaust valve starting to open. #1 is front driver's side.Back up a little and set the crank timimg mark on 0 on the degree marker. That should be TDC. Put the rotor button on the distributor and set it roughly at the 3 o'clock position and put it in. As it meshes with the cam gear it will turn and once fully seated should be at 5 o'clock. that is the position of #1 plug wire. If it's not at 5 o'clock pull it out and turn the rotor button slightly to catch a new tooth and reinsert. DO NOT force the distributor into position. Wiggle and push,turn the rotor slightly and it will go into place. Patience is the key here and make sure it is fully seated on the intake. Once it is in place the firing order is1-8-4-3-6-5-7-2 and the distributor runs clockwise. Odd cylinder's are on the driver's side and even on the passenger's.
You may have to adjust the distributor a little one way or the other to get the engine to fire. That's normal. Once you get it running you can set the timing with your light. If you have no light then advance the distributor until it start's to sputter and do the same in ******. Then set your timing in the middle of that space, that will get you close. Hope this helps.
