Phenolic Spacers

[jonalley]

So where are you buying these spacers in multiple thicknesses or are you making them yourself? McMaster Carr has a phenolic coated baltic birch ply in sheet form that could be pattern routed.Regards, Jon

Any form of insulating spacer makes some difference, but the carbs will still get heated from the engine and exhaust.
The inlet manifold heat still conducts to the carb base via the studs/nuts.

I have found mounting the carbs in a heat shielded box and letting the outside filtered air to run around the bottom of the carbs prior to the top keeps them cool.

Fully isolated insulators with studs top and bottom isolate the carbs better, but near impossible to fit on a V8.

Google Weber phenolic spacer. Lots of places sell them

I agree with jonalley, I have the phenolic spacer and had them in my 1967Volvo GT 123 with twin Webers 45 and they work like a charm. Do mind the hood clearance.
