I have been trying to start my 1950 pontiac, and was thinking of putting in a new distibuter, . I have a brand new delco distributer #1110232 with vac unit 1116077 and my book calls for a #1110219 with vac 1116051 , the new one I have been told is for an automatic, whereas the one on the car is for a standard. can anyone tell me the difference . also what is involved in the removal and reseting them, asa I have never done one

thanks bill in red deer

by the way both look identical

most of the time, if the outside is the same, the difference is the the spark advance curve.

Today with the sunday drive on those car the curve advance should note be a big issue to live with unless you want the maximum performance of your engine with any loss of power.

In some case the automatic or manual powerplant don't have the same engine compression ratio, it may explain also the different distributor number and by the way the spark advance curve.

The safest way and quickest it to remove the distributor cap, located the position of the rotor, no matter if the engine is in #1 cylinder in compression phase. After remove the distributor.

When you put back the new one place the rotor a bit forward or reverse from your needed rotor position, it's because the lower gear angle will rotate the rotor as much as you push in the distributor in the block. Don't worry it may take 2 or 3 try to reach you needed rotor position.

Connect your wire and fire it up.

You can use the #1 cylinder at 0 degree method if you wish, it will make you a step more to do the job.

hope this help
