Default Spark plugs too lean???????
When I changed my plugs today I noticed the tip colors were tan/tanish white, tail pipes are close to the same, is this too lean or am I good to go?? For 79 L48 350 stock. Thanks!!!!!

Sounds right for a stock engine

Sounds like generic no-lead deposits.

Tan plugs and a matching tailpipe? Don't get all excited and change anything- you'll mess it up.

My spark plugs are tan too, but my tail pipes are much grey/black.

I suggest you step a little more on the gas pedal

Hello,

White is too lean.

Brown/Tan is just right.

Black is too rich.

Black oily, your oil rings are shot.

Good Luck!
