A good friend of mine and customer stopped by the shop to say hi. He drove his '79 40 series with 59K on it to the shop. He asked me to take a look at the dist as he thought it was loose. I suggessted he start the truck. One big click but the starter would engage just not turn the motor.

We tried to bump it then we dragged it. Motor is siezed. The dist clamp is still in place in the correct location but the dist has risen up around 1/4" and bent the clamp cuz it is held to the block.

I guess he dropped oil pressure and siezed it but WTF caused the dist to be pushed up so hard it bent the clamp? I am thinking a broken cam or spun cam gear but it drove just fine the 5 miles he traveled to the shop. Maybe an act of God but at least the cruiser knew where to come to die.
 
If the dizzy seized it would provided the neccesary resistance to make the gear climb the cam gear.

Pull the distributor and see how tight it is.

Didn't notice there was no oil pressure, eh? To bad. It's a shame such a low mileage engine has to be rebuilt.
