Insulating Against Heat on the Carb

1969VADart said

So I will revisit my question one more time from previously, is the thinner Edelbrock heat insulator gasket (0.32" or 5/16", whichever) better than a slightly thicker (1/2") wooden or phenolic spacer? I see a lot of good ideas, but didn't really get an answer to this question. I appreciate all of the input to this discussion.

If you have room, use the 1/2". If you don't go to the thinner .32. It just prevents (insulates, blocks, etc) heat transfer from the intake to the carb. I don't think between the fiber, Phenolic or wood/laminate ones you'll see a huge difference between and i believe you will hit a diminishing return with even thicker spacers. Use what fits.

On my car with a Weiand Stealth I need all the room I can get and age and type of mount and intake air cleaner can vary. It just prevents (insulates, blocks, etc) heat transfer from the intake to the carb.
