Anyone ever done or heard of this? about to button up the rest of my 357 & someone mentioned painting or coating the underside of the intake, would help with keeping air/fuel mix a little cooler/ heat issues?

yeah that was my first thought of what would happen, why I asked the question lol.
just never heard that before

It works, and if you prep properly and use the correct paint there is no reason why it would flake off, it's all in the details. Small things like this alone do little but when added to other small things you go faster eh.

what kind of paint would you suggest? not just regular ol high temp paint I dont think?
What you are referring to is a thermal barrier coating, not just a paint. It is usually done by a specialist shop that deals in that sort of thing, like Swain. The price is usually pretty expensive, but it can be worth it in some cases. It is not something I have ever tried though, too rich for my blood.

x2. For something like the engine masters challenge where you're trying to squeak every tiny bit of hp i could see it. On a street or street/strip car I'd say your money would be better spent elsewhere.
actually it's an old school trick. you paint the intake white to reflect the heat instead of the metal absorbing it. plus paint aks as a minor thermal barrier. radiators and heads are usually painted black for the same reason. the black will absorb and radiate the heat outwards.
I have seen this done on a few cars over the years. All they used was the high heat exhaust paint. I can't say weather or not it helped (it's susposed to). But I can say I have seen a few of these intakes removed after a couple years of use. And no paint flaked off. Just prep it good, and bake it in the oven.
I painted the lifter valley of my engine with regular engine paint and everytime I pull my intake for intake swap or porting, it's never peeled. If that don't peel, then I'd say they bottom of the intake wouldn't be any differant. Just make sure it's good and clean and use a white engine paint.
