Any idea what ran these? I just picked up a 76 f250 with a FE, I was told it was a 390, appears to be a reman., the factory 4 bbl intake has a liquid cooled carb spacer, the spacer and/or intake could be from a different engine. Any ideas?

 

It's for heating the carb, not cooling. Helps warm up, helps fuel economy by heating the fuel for easy mixing with the intake air.

Possibly from the early '60s.

Any numbers on it?

 

I thought it was mainly for keeping ice from forming in the bores during cold weather?

Under vacuum, air cools, so even if the temp is above freezing, the vacuum side of the throttle plates can get cold enough to freeze water vapor. Ice on the throttle plates is not good, eh?

 

Ive picked up a few of these spacers from my local p&s yards they are both
2v and 4v. I believe they were from 70s vintage trucks but I was not paying attention to the exact years for which they came out of.

 

My '69 360 had a 2bbl and one of those coolant plates on it. Promptly got thrown in the trash.

My '67 352 2bbl truck didn't have one. Was it a build location thing? Only in certain places it was an option?

 

As long a time that it takes my FE to heat the water, hell would freeze over . I think it's for icing also and the exhaust cross over in the intake manifold should provide enough heat for vaporizing the gas. I've seen both, with and without..

 

All the FE's I've been around warm up really fast. The exhaust cross over does NOT provide enough heat. The carb spacer doesn't either, but it helps a lot.

 

Well if you have an aluminum intake and want the heat, then the spacer is the way to go, at least then you could block off the cancer causing gasses to the intake. You could also install a valve in the heater hose to block the hot coolant off in summer.

 

The 390 I yanked from a '63 T-bird for my highboy (about 8yrs ago) had the carb coolant spacer as well (4bbl version), I live in MT. so I just left it in place.

 

Boy do I have a story about the cancer on an aluminum manifold
