this may be common knowledge

alright, when you're ready to put your distributor in, how do you align it so your timing is where its supposed to be? i.e. not sparking while the piston is in the exhaust stroke.

pull the number one plug out,put your finger over the hole have a friend bump the motor over till the compression blows your finger off( i said over the hole not in it) than look at your timing marks they should be getting close, if you can, move the motor by hand till the marks line up, than drop the disibutor in and the rotor bug should be coming up to the number one plug wire on the cap, you may have to use a screw driver to turn the oil pump shaft to get it to drop in.

Doc here,

Number 1 cylinder TDC compression, Timing marks aligned, Both intake and exhaust valves closed , no pressure on the lifters (not too much slack either..) If you can't co~ordinate these, you have timing chain/gear issues..

Drop the dizzy in, and watch the rotor, It will advance clockwise a bit, this is because the gear teeth are diagonal cut, It will go about a tower in a half in some cases..Note the amount of change and then withdraw the dizzy.

Line the oil pump shaft up to that location with a large screw driver, and reset the dizzy, for number one plug tower, allowing for advancing as the gears seat..

The easy way to do this is make magic marker lines on the base of the dizzy, for exact #1 plug tower, and the difference of rotor movement as it seats..due to the cut of the gears..(I.E...#1 and the amount of distance BACK required to make it sit on #1 plug tower when bottomed out..)

#1 plug tower in the stock location for SBC's is 5 to 7 O'clock, (depends on year, and obstructions) 7 is usually good.

Direction of rotation is clockwise.

The F.O. is 1 8 4 3 6 5 7 2..

Put on your hold down just tight enough to hold it but enough to forcibly move it by hand, and start it up..set your static and total timing..

Static 10 to 12 is a good starting point advance defeated and vacuum line plugged.

Total around 34 to 36 is usual on a stocker with advance hooked back up..

Tighten down the hold down, set your idle for 650 Manual trans, 950 Automatic, and drive it .. hammer it on the freeway, If it pings or runs hotter than usual, retard it a few degrees..If it dogs, advance it..Try also lugging it up a steep hill highest gear as slow as it will pull, If it pings check the timing again.

That's it.

Doc
