Timing marks 350 engine

I have a 350 engine that is dieseling after the engine is turned off. I read in a thread that advancing the timing and reducing the idle can help cure this. So went to check the timing but I can't find the timing indicator arrow. The harmonic balance has the timing marks but there is no pointer/indicator on the block. Or it's hidden. They installed power steering on the car and the pump and bracket partially obstruct the timing strobe. I did read you can also time the engine using a vacuum gauge?? Any body have any thoughts? It has a Mallory electronic ignition.

Re: Timing marks 350 engine

Hum well it isn't the easiest thing to find but a strong flashlight or shop light will see the pointer, but yours maybe M.I.A. broken off or something.
The marks can be enhanced with flour or chalk.

You can TUNE an engine with a vacuum gauge but can't read the TIMING that I know of.

But lets get the information missing from your signature as to is she: 67, 68, 69 350? Automatic or manual transmission? SMOG installed and working or removed? Original Carb?

Re: Timing marks 350 engine

Depending on the year of the engine, and the water pump design, timing scales were moved. Later engines had the long water pump, and had a bit of clearance between the timing cover and back of water pump. For these engines, the timing scale was on the timing cover, above the dampener, at the noon position, visible by looking down between the back of the water pump and timing cover. Those engines were done that way to allow for the extra bracketry added for accessories, belt drives, and most obscure the side mounted timing scales, so timing could be read from the top of the engine, not from the side.

A short water pump setup won't have the open area between the back of the water pump, and timing cover. They all read from the side of the engine.
