Plastic And So-Called Phenolic Carb Spacers

I have for a couple years now use a 1” thick laminated wood open spacer on everything thing I can.

I used one on my stock stroke 360 with an Air Gap manifold.

Here’s a picture of one on a supercharged 408. I’m turning this blower a little too fast because it’s too small for a 408, so I’m experiencing a little more hotter intake temperatures, the blower is like an oven, Using a 1” thick wood open spacer really keeps the heat away from the carburetor.
After driving, and putting my hand on the blower, it’s hot. When I touch the carburetor, it’s luke warm.
I believe it really helps. After Driving around all day, I can park it for a while, then come back and it fires right up. No heat soak, or the need to crank and crank until it starts.
