455 problems
I have a 72 delta 88 with the 0riginal 455 and sometimes when i go to cut the car off, the engine makes a clunk noise and wont cut off. I can turn the key back to the on position and the car comes on like it wasnt off. does anybody know why and what i can do to fix the problem. 1 more thing... when i start my car warm or cold, grey smoke comes out the tail pipe for like 5 seconds. any suggestions...

The smoke on start up is from the valve stem seals being bad. They get hard a brittle and crack off. Due to old and high mileage.
The run on after the key is off, is from carbon build up, most likely from the stem seals being bad. When the car is hot, this is common, also alot of slow driving doesn't help.
Might want to run some carbon cleaner thru the tank.

He says it runs on when he shuts the key off. With the ignition off, there is no spark so timing is irrelevent. Running carbon cleaner is the first thing.
He also needs to check for high idle speed and also check everywhere for vacuum leaks. These three things are the biggest cause of "dieseling".

Watch the seafoam. I like it and use it on all my old cars when i first get them. I use the sea foam bofore i change the plugs. I have seen a few times the sea foam foul out the plugs. So sea foam fist, new plugs next. Then some burn outs! LOL
