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: HEI DISTRIBUTOR PROBLEMS

on the intake manifold you will see 8 numbers, this is your firing order
from the front of the car the left side numbers are 1,3,5,7 and the right side are 2,4,6,8. now ont the distributor cap there should be a number 1 at one of the plug towers. you start there with #1 plug wireand continue.
on a chevy the firing order is 18436572 and this is the order you put the wires on the cap. now the second problem i don't know right off hand which way the rotor turns on your engine. so remove the cap and crank the engine over and see which way the rotor turns, this is the order you put the wires back on the cap. hope this helps

SOURCE: What is the distributor timing mark for 89 chevy

Is the vacuum hose removed from the dist when the timing is being checked?
Are you connected to the first plug wire (closest to the rad) on the drivers side?
If this is being done.....remove the cap and rotor and check the springs on the mechanical advance,the advance should be tight to the shaft and springs tight.
I would set the base timing on this set up .....at idle speed...... at between 5 and 10 before TDC.

Remember......timing marks on modified engines are not always accurate. Parts from this year and that year put together.

I have a 1972 Pontiac 455 7.5 liter motor in my car.It may run for short time spittering and sputering then die, I may be able to start it again or may not. If i do it just dies.


Sounds as if you have either a fuel system problem or bad ignition. Star with ignition as it is easier to troubleshoot (IMHO) If you are running HEI distributor, have module tested. If running points, examine them carefully and replace points and condenser as needed. For fuel system, use gauge to test fuel pressure. You can also disconnect line to carb and stick it in 16 oz glass bottle, crank engine 10 seconds and see if you pump1/3 to 1/2 full (I think that's the approx amount--been a while since I have done this. If car has been sitting not run for a while fuel in tank may well be bad.

used less .043 or whatever

1996 chevy silverado v8 4.3 won't crank. Replaced


Check the voltage coming from the battery and check it again at the coil.I suspect you are not getting the proper voltage going through. Clean all the terminal ends to bare shiny metal and make sure all the connections are tight. If I remember correct your truck still has the HEI setup with the coil in the top of the distributor cap. If all the voltages are good, 12+ volts you should replace the coil. Hope this helps.

Do timing gears on 1972 v8 pontiac both face up or face each other


It doesn't matter, IF you have not disturbed the distributor. If the distributor is out, then when you put the cover on, the marks should face each other. Just to make sure, when turning the engine, put your finger over #1 spark plug hole, slowly turn engine, when air blows out, turn engine slowly to the timing mark and set distributor to point to #1 cylinder on the dist cap.

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

No fire


if you have an hei distibutor you need one 12 volt wire when cranking and running to the distributor. that is all that is need to hook to the distributor to run.the distributor will have a plug from the module that hooks into the cap/coil. you also have a tach hookup on the cap.
