Old Ford owners would know. In the 60's part of 70's many MANY Fords heated the base of the carb by means of what looks like a carb spacer plate. It was hollow and had heater hose connections. Engine coolant both heated and moderated carb heat.

We also used to use/ see them occasionally on a six with a 4 bbl intake to provide carb base heat.

I went to Clifford's site, no go. Googled, searched Efray. Can't find 'em in Summit's catalog.

Making one seems like a real PITA. Just getting that large a block of alloy, and trying to cross drill it accurately would be a deal for me. I do have an old Jet "drill mill."

I'm actually hoping it will COOL IT DOWN, IE the coolant might just be cooler than the heated intake crossover. I'm also thinking that if I can figure a way to tap into it's coolant source at the coolest point in the system, IE the outlet of the radiator (bottom)

I'm ALSO thinking of installing a few turns of metal tubing in front of the radiator and running the fuel through THAT


Find one of these on a marine application?
 
My old BMW had one on it but for the life of me I cant remember what its called either.
 
no way do i think that will cool it....

your better off going with a phenolic or "wood" spacer...
 
They were on my Dads old Ford work trucks, but I do not remember what it is called neither......

Ford Service manual: "To prevent carburetor icing at the base plate, a spacer, heated by engine coolant, is located between the carburetor and the intake manifold. The coolant flows from the front of the engine through the spacer inlet hose into the coolant spacer and into the heater hose to the heater core"
 
Actually I would think 160*- 180* temp from this would be MUCH better than 350* - 400* crossover temps.
 
I think your over thinking things, But the fuel line in front of the radiator is a bad idea
 
When a hot engine is turned off the cylinder heat would go there
( the highest point ).
 
Never know till you ask. They might even have something since 318's were used in marine applications. I don't know if the 318 is the same bolt pattern as the 273 though.

this is true but being the temp of where he lives is unknown, i might not be an issue... besides... i would think a closed hood (no scoop) engine compartment would have plenty of heat being flung around to keep it warm enough to not freeze up, even with a spacer

with a phenolic or wood spacer the carb would never see that... also what about the hot air thru the rad????
 
Well guys I had the best luck finding some on eFray searching for

Ford, "carb spacer." All are used of course. Many have the same no, C5AE-9A589

I was hoping to find a new/ aftermarket new spacer. I may just buy one of the Ferds, and investigate getting a chunk 'o material that I can use to make my own if the Ferd one is flakey.

We'll see.

The good news is we're having April in July, here, so far it's been fairly cool.
