Take the #1 spark plug out. Plug the hole with your finger while you rotate the engine by hand(with ignition off and coil disconnected for safety). When the piston is coming up to top dead center you will feel air start to push past your finger. When the air stops, you are at top dead center.
Then look at the harmonic balancer and set it to 8 to 10 degrees advanced. After you have done both of the above, install the distributor as per instructions.

If you did not bump the motor, rock the car while it was in gear or some other such action and properly marked the dizzy body and rotor from the way it was after the dyno run then you'd have to be a bunch off during the reinstall to not have the car start.....in which case follow the directions above. I'm growing suspicious of the points conversion.

Once you're convinced the plugs are routed properly and dizzy is in correctly I'd hold the ignition coil high tension lead near a ground while cranking motor - you should see a nice fat spark..

I don't know if that would hurt your Crane conversion but instead you can hook up a timing light to #1 and see if the light strobes while cranking...

I think it's the flux capacitor.

He needs to start with the basics. The white puff of smoke is making everybody immediately point to something that may not be a problem. A slight puff of smoke from a small carburetor cough could have drifted back towards the distributor and coil by the time he stepped out of the car and looked in the engine bay.

I moved past the smoke being electrical once he said the shielding was off.....
Its timing most prob.

Just for grins I'd still be tempted to pour a couple of ounces of gas down the carb throat and try cranking again WITH THE AIR CLEANER ON....

I've blown a muffler casing almost in half from trying to start a car with the dizzy 180 degrees out, so I'd suggest against that.

You're no fun at all.

I've singed off my eyebrows, mustache and all the hair in my nostrils looking down a carb that backfired with a nice fireball many decades ago. (Hence the air cleaner recommendation!)

Since you have just reassembled this engine, is it possible you left a large vacuum fitting off (carb or manifold) leading to a lean mixture and a source of vapor upon back fire?

OK, this is a point of confusion/stupidity: How can I move the HB when it moves with the entire crank assembly? How am I going to rotate the engine by hand? It seems 8 cylinders, trans,fluids would make that impossible even if I could get my hands on ? to turn it over.

Possible but I doubt it. I'll check.

"Flux capacitor" Like in Star Trek? I thought those appeared only in '68 and later.

In the center of the harmonic balancer there should be a large bolt. Find the socket that fits the bolt and turn it with your socket wrench.

His profile indicates he has a 300 engine. No bolt unless someone added it.

If it's a manual transmission, put it in high gear and rock the car until the crank is where you want it.

Sometimes, you can grab the fan belt and turn the engine.

Pull all the plugs and life will get much easier to find TDC. Where are you?Maybe someone is close to Help. Al W.

Progress report:

I checked the plug wires- they are new and where they belong

Took the dizzy cap off, disconnected the coil wire and started bumping the engine around to see if I'd get lucky with 0 TDC. After about 5 bumps, the wispy white smoke appeared again, same place-behind the diz above the bell and in front of the wiper motor. Disconnected the Neg cable. Checked for heat in obvious places and found none. Don't think the carb burped enough to form a vapor that could have been suspicious "wispy white smoke". Not going to attempt re-setting the dizzy until I find the source of the smoke. WTF is going on here?

Put it back together then pull a plug out and keep it hooked up and ground the treads of the plug to something Then hold it with a pair of well insulated pliers and have some one try and start. If you have a spark in the plug you know you have fire. If you don't. Then you know where to look

What about the smoke? Last thing I want is an electrical fire.

As far as the electronics go, the only thing different in line from the dyno is the ballast and my coil. Crane says the XR-i keeps the ballast in line. I don't get it.
