This should do it.
You can also do an internet search for a standard 350 Chevy engine.
The firing order is 1-8-4-3-6-5-7-2
The order is the same for engines from the mid 1990s back to the late 1970s.

SOURCE: need wireing diagram to change 72 nova over to hei distributor

Hey , just take the positive wire from the coil you are removing and feed it to the + terminal on the HEI dist. cap.the other terminal under there is for your tachometer. If you are mounting a master kill switch in the bumper for drag racing- attatch the kill wire to the tach terminal also.
Thats it you just plug the three wire pigtail from the dist. base(pickup) to the cap and you are off.
Remember firing order is 18436572 in a clockwise direction. to find #1 remove #1 plug and have someone"bump" the engine over while holding your finger over the hole-carefull. then line up the slotted mark on the crank pulley with the big notch on the timing indicator. Good luck

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: wiring an hei distributor

You shouldn't need a spark box because thee coil is located in the dist. cap. You need to run a 12v switched power source to the side of the dist. cap that is marked dist. if it isn't maked it is the term. that is on the front right of the conector pad. the one on the left is for hooking up a tach.

Chevy express 1500 will n ot start, fuel pressure good 60 psi! The coil is sparking good! the engines turn over strong. it seem to do this whenever it rain!


check for spark at the spark plugs, there have been a lot of trouble with the distributor caps and rotor. Be sure it has the correct AC Delco spark plugs and good wires. Be sure to use AC Delco or GM parts.

I have a 1999 chevy suburban 5.7 Vortech witch is starting to drive me nuts. The spark plug wires, and all around the ignition coil is arching. With this said the distributor, cap, rotor, plugs, wires, and...


Assuming none of the wires are crossed, AND you replaced the cap rotor wires with quality replacements (meaning AC Delco) then you may have a bad coil. Remove coil from dist cap if HEI and look for any signs of arcing such as blackened areas.

Wiring for a small block 350


need to know if its a HEI cap and rotor or not. HEI caps have the coil built into them , an all in one ignition as compared to a external cylindrical coil.
you need to know that. either the distributor cap is a huge hurken thing (HEI) or it has an external coil somewhere or the cap has a ninth distributor hole in the middle of the cap to put a coil. wire.
after you figure out which one it is then you have to either go to www.autozone.com and study chevy wiring or buy a haynes manual for the similar vintage engine. for the external coil I would try a chilton manual for a chev truck before 1972. for HEI anytime thereafter. I may be off by a few years on the age of the engine. but hopefully you got an idea of what to do, or just google chev engine wiring? and study away.
good luck

Chevy 350 no spark I have changed the coil, cap, and rotor. Still no spark. I also changed the plugs and wires about 3 months ago


Check the distributor module (ICM), it may have gone bad and needs to be replaced. It's around $40.00 and it's under the rotor in the distributor assembly. Check the red lead wire to the HEI for voltage, there should be 12 volts. It common for the ICM to fail on the HEI system and if you go to Auto Zone, they can give you the step by step instructions to replace the ICM. Good luck and keep me posted, be glad to help.
