Help on a 1990 350 distributor

Where is the number one plug wire? The cap is not marked.

#1 is the terminal closest to the coil. They line right up.

If that's the same small-cap computer controlled HEI that my '91 truck had, or a standard HEI, the #1 plug is whereever the rotor is pointing when you're at TDC after the #1 intake stroke. That could be anywhere if the distributor has ever been removed.

Re: Help on a 1990 350 distributor

generally, it's a good idea to just install the distributor with the rotor pointing towards the #1 cylinder. the #1 wire goes on whichever terminal lines up with the rotor.
makes it easier if you ever decide to tear it apart down the road.

you don't plan sincerity.
you have to make it up on the spot.

wanna hear about 20 years ago when i was too smart to know any better?

I meant if the distributor was the way it came from the factory.

Of course you could put it anywhere you want to. I thought the question was where it should be.

Re: Help on a 1990 350 distributor

You can search the achives and find the answer. With the engine on #1 TDC, the rotor should point in the direction of cylinder 1. Otherwise, the vacuum advance canister will limit your adjustment on the timing and the wires may not reach.

18436572 should be the firing order.

You might have to twiddle the oil pump shaft to get the tang to line up with the end of the distributor. Also, as you set the distributor in place, it will want to rotate as the helical gears mesh. As a result, you have to lead on it a tad so that rotor points toward #1 as it seats on the oil pump.

Re: Help on a 1990 350 distributor

I think you are talking about the GM Small bodied HEI with the externally mounted coil. My 91 pick-up had this. According to my Haynes repair manual there should be a raised 1, marked on the distrib. cap. This should be your number 1 cylinder. If your cap is definately not marked ,rotate the crankshaft until the timing mark is at "0" ON THE COMPRESSION STROKE. and see where your rotor is pointed. This will be your number 1.
