Can some one tell me how to do this the right way or does it mader or can you put it in and you have to put the timming light to it . can some one give me some pointers .That would help me out alot. Thank's 70 Nova

[crazy larry]

well i'll try...
1. rotate engine to tdc of compression stroke, no. 1 cylinder.
2. locate no. 1 plug on the dist. rotate the rotor about 35-45 degrees before the no.1 plug location.
3. slip it in, rotating carefully to engage the cam gear, as it goes in, it'll rotate due to the gears, and with any luck it'll line up right.
4. attach plug wires to proper plugs, and corresponding cap holes...
see if it'll start, backfire thru carb = 180 degrees out, remove and turn the rotor 1/2 revolution and try again.......

did i forget anything.????????????

Place the rotor 35 degrees before you insert the dist.

Once it is in should is be about 10-20 degrees after (past) the #1 post. Right?

Of course these are at ~9 deg PTDC

-----------------------------
This would mean that as you move the Vac can away from the fire wall you are advancing it. Right?

Just some problems that have plagued my recent rebuild.

[GoneNova/406]

pull #1 plug out have someone put their finger over the plug hole while you bump the starter around slowly.if you don't have a helper use something just a hair bigger around than a spark plug so you can stick it in the plug hole.when you bump it around and it comes up on #1 it will make a fairly loud popping noise and the item will pop out of the plug hole.as you drop the dist. in point the rotor at about # 5 cylinder and as you drop it in it will turn to the r.when it is in it should point to # 1 on the dist.cap.replace everything else.your vac. canister should be pointing approx.to the back top bolt on your passenger side valve cover(old style covers).as you begin to start it you may have to turn the dist. one way or the other.to fire wall retards/to front adv.when you get it to the point where it will run put the light on it.

[webwiz2600]

Alright did all that.

Now I can start it but the timming will jump from 10 deg. adv. to 90. Is this caused by a cross fire or over laping spark wires?
Could this also be caused by 2 cylindars firing at once.

I would add: Line up the slot in the oil pump shaft so it points to #1. The install the distributor so the rotor also points to #1. Phil

To Install your Distributer Properly, Try this:

• Bring your #1 Cylinder up on Compression TDC.
• Timing mark should be TDC
• Both intake and exhaust valves should be closed (slight play in lifters)
• Locate #1 Plug on the cap and set the rotor tang at that position. (mark the distributor Body with a pen at that point so you can see it)
• With the rotor pointing to #1 plug look at the bottom of the Distributor shaft and note the location of the oil pump key slot, using a long slotted Screwdriver set the pump shaft approx. that position.
• Install the distributer. Because of the diagonal Cut of the drive gears, The rotor will turn as you insert it, so figure the distance between the amount of turn, and the line you made on the distributor body and rotate it back that amount, It Should Seat Exactly on #1 on the cap, or very, very close.

After you have that right, Check your Firing order.

The spark plug locations are :

Driver's side front is #1,

Passengers side front is #2:

IE the left side will be 1 3 5 7,

The right side will be 2 4 6 8.

The Stock location of #1 plug on the Cap, should be, about 5 O'clock.

Direction of rotation is Clockwise.

Firing Order is: 1 8 4 3 6 5 7 2. (see photo)

If you have this right, It should Fire right off!

Set your Timing with a light, check to see what the setting and at what rpm you need to be at for your engine, And be sure the Vacuum advance line (if so equipped) is removed and the Vacuum line is plugged.

Hope it Helps!

I'm aware of all of this.
However I was setting my initial timing. Setting the TDC mark on the timing chain cover to ~10 degrees on the dampener. I was then setting in the rotor pointing to the 1 post.
Is not setting both to TDC causing to much advance?

If I read and understand your post right, you are setting the Static timing at the crank at 10 degree's?? , and the distributer on #1 plug on the Cap??
If so it's way off...more than advance / retard can compensate for..

Static Timing MUST be at #1 TDC Compression... To add 10 or 12 degrees is done by advancing / retarding the distributor while running and checking with a light at the marks..

That is If I understood what you said..I have my bad days... selective endorphin misfires... happens when ya get to be an Ol Geese...

Yes!
I'm setting the balancer to ~10 deg. Then placing the dist in pointing at 1 post.

In the morning I will line the dapener TDC with the timming marks TDC and then place the dist w/ the rotor at the 1 post.

My dad (in his hey-day built many SBC and BBC engines) but this has whiped are butts . I hope this works!

[I quess this is of topic but...]Could that much advance cause a deep knock in the engine. Almost sounds like a rod.

[color=yellow][size=2]Doc Here

I suppose it could if you were way over~advanced.

[webwiz2600]

Alright. I got the TDC's to line up as close as possile (maybe 3 deg.s off). Now I can't start it no mater if I move the vac can to the firewall or to the manifold. (of cousre a little at a time)

It'll try to start but then backfire or start and then turn maybe 1-2 chuging revolutions and stop. I guess it is a type of desieling.

Any Ideas Guys?
I've come from the elcamino central board (I guess I stumped them). Can Ya'll show them up?

[coldknock]

If it's at all possible, rotate the engine by hand/long ratchet. Using the starter will cause it to fly right by tdc on compression and come back up to tdc on the exhaust stroke. Take the valve cover off and watch the intake valve closing. When it closes and the piston reaches tdc that's the correct position. Then follow Crazy Larrys directions.

been there done that.
sorry

BTW - nice pics!

[willys36@aol.com]

I ALWAYS carefully set the engine to TDC on the compression stroke and install the distributor @#1 terminal. Then I fire it up and find it 180deg out! No matter how careful I am I always am out 180deg!!
