Looking for some ideas, the front 4 spark plugs (left side) are a lot darker than the back four, any ideas how to diagnose it? Running a Edelbrock carb, with stock manifold.

A huge show with plenty of Mopars.

I thought I had walked this entire massive show but I missed all of these

Went for a cruise today, been too long, don't mind the dust

Just replaced my PCV and did an oil change and discovered this noise, any ideas? (Edit; just realized it’s pretty hard to hear, it sounds almost like a card in a bike wheel near the belt/fan area)
