Between 8 & 10 initial works well.

Be sure to disconnect and plug the vacuum hose while you set the timing.

i didn't crank the engine or anything wen i took the distributor out of the car so i figured i didn't have to set cylinder 1 back to TDC...wen i finished working on my distributor i popped it back in exactly the same way i took it out (i marked the location of how it should go back in) but now it won't start....it started fine before i took out the distributor, but now it'll crank but won't start...someone please help me out!!! i wanna take my car out for a joy ride tonite but if i can't get it running imma have to take the rice burner(toyota camry) out...

if u need uhmm more info on wat i did just let me kno and i'll tell u wat i did to the best of my knowledge

I'd start by making sure you have spark before anything else. You can crank it with a wire off with a plug and see if there is spark.

Did you mark the location of the rotor on the dist,and then the dist location on the block.When you put the dist back in the rotor will turn.So you have to move the rotor back one or two theeth to get it to line up.It takes me a couple of trys to get it right.Or you can just start over and find top dead center on #1.

JAAZZY - yea i kno there was a spark....i got one hell of a shock....i need to remember to use something else to hold hte wires next time....

Fastymz - yea i marks both the block and dist but i already cranked the motor so i'm thinking i might have to start all over again...unless i don't have to since i put the dist in before i cranked it? if worse comes to worse its time to find TDC again

Yes, start over.

Pull the #1 spark plug {front on passenger side}, stick your thumb over the hole and tick it over until you start to get compression, then turn the engine by hand to TDC on the balancer.

Find spark plug wire #1 on the distributor cap, match the rotor to it and drop the distributor in. The rotor will turn as the cam gear engages, so double check the position of the rotor and turn the distributor until the rotor lines up with the #1 terminal.

Fire it up and set the final timing.

In order to set initial timing on my engine, I use "the pencil method". The reason I believe in this method is because the timing marks on harmonic balancers aren't always exactly correct, especially if the balancer is old. I know for a fact my balancer is a BIG liar!

I take out the spark plug on the #1 cylinder and put a long, brand-new pencil into the spark plug hole. Make sure the pencil is long enough to sit on top of the piston and still stick out of the hole.

I then turn the engine over by hand while I watch the pencil. (NOTE: I have to take ALL the spark plugs out in order to have no compression, so I can turn the engine easier...I'm a weakling, OK?) Anyhow, I watch the pencil VERY CAREFULLY and I try to see when the pencil is sticking out the farthest. When it is sticking out the farthest, the #1 piston is at the top of its compression stroke. I immediately stop turning the engine and go to the distributor.

I take the distributor cap off and I notice where the distributor rotor is pointing. Where it is pointing is where the contact of the #1 cylinder should be. Carefully rotate your distributor's body so that the contact in the distributor cap for the #1 cylinder spark plug wire lines up with where the rotor is pointing. (You will have to take the distributor cap on and off to make sure you have the alignment right.)

Once you have the #1 cylinder contact lined up with the rotor, your engine is perfectly timed. Tighten down the distributor hold-down clamp and start the engine.

Drive the car, and get up to about 45-50 mph. If you notice knocking (pinging), then you need to either switch to a higher-octane gas (I run only premium in my car), or more likely you will need to fine-tune the timing.

well i got my car running finally and watnots...but now i got another problem...i set the timing at 6 degrees as it says in the shop manual...i hope that's right...

if i read everything rite i'm suppose to set the timing with the vacuum hose off then put the vacuum back on wen the timing is set rite?

my new problem is that wen i set the timing and then put the vacuum hose back on....everytime i try to accelerate the car stalls...but if i leave the vacuum hose off then i don't have a problem accelerating....what can be wrong? i kno its not the carb cuz i just had it rebuilt and tuned and the car was running perfectly before i took the distributor out...uhmm anymore insites ads to wat it might be?

oh yea by the way u guys rock! i swear...so far everytime i needed help with my car i get like a flood of answers to help me out i greatly appreciate it!

I've been racing a stock 289 for a few years, so maybe I can help.. Some 289 distributors have 2 vacuum tubes on the dist. The tube closest to the dist. is for retarding the timing and the one toward the front of the car is the advance.. You should use this one to hook the vacuum to.. The retard is not necessary.. When the vacuuum advace is working properly, you should notice that the timing will quickly move ahead by opening the throttle a little bit..

I have also found that 6 degrees of base timing is usually not enough.. I always ran mine at 10-12 degrees for better acceleration and fuel economy..

Hope this helps,
dan

Like Dan I always ran about 10 initial with my 289s. They seemed to run best there. This is on daily driven vehicles. I am running about 12 now with my 342.

Good job, Fuzion!

They're right, try 10 degrees.

When you have $100 to spend, I highly recommend getting a Pertronix Ignitor and matching Flamethrower coil. They are well worth the money and you'll never have to worry about points and condenser again.. Better starting and performance for the street/strip..
