How To Find Top Dead Center On A Chevy 327?

On my commuter car, which has a hemi style head, I remove the spark
plug and insert a long narrow diameter plastic rod. I put the car in
neutral and rock the car back and forth until I know I'm at Top Dead
Center.

How do I find Top Dead Center on an engine like a Chevy 327?

Same way.

If you put the car in neutral, rocking it won't turn the engine.
Maybe you meant you put the car in top gear and rocked it
back and forth until the plastic rod projected out the furthest.

You can find TDC on the 327 the same way. Or you can
just turn the engine over until the advance scale on the
vibration damper is at zero. This is TDC for cylinder 1.

Good luck.

no because you can never trust a small block chev vib dampner to not
have slipped. that is why you check for true tdc. KB

You have to make sure it is TDC on the "compression" stroke. There are
two TDC's in a four stroke.

They also make a "whistler" that I use. It's bout $10. You screw it
into the number one cylinder, turn the engine over by hand, and whn it
stops whistling, you are at TDC on the compression/firing stroke.

Pull number one plug. Put a long ratchet and proper socket on the damper
bolt. Put trans in neutral and rotate the engine with your finger over
the spark plug hole. You will feel the compression try to push your
finger off the hole. When the pressure stops your at TDC on the
compression stroke. The damper line should line up with the 0 mark on
the pointer.

Underline this statement. Lots of people miss this fact and get 180 degrees
off with
the ignition.

Been many years since I had to do this but it was not a mater of
getting the car "exactly" on top dead center, it was only that I
needed to get the distributer back in and needed it within a few
degrees. Never saw one of those whistler things, I would have bought
one. But I use a piece of tissue paper, wadded up and placed into the
#1 plug hole. Always turned the motor over with the starter, disable
ignition, and when the paper flies out if you stop cranking
immediatly, it is now on TDC. Rather simple and it works for me.
