Phenolic carb spacer...CAD drawing

They have one for the three bolt 94's and it works the same as a pheno spacer.

I saw the link you mentioned and it is very interesting.
I am doing this in order to isolate the heat from the engine. I notice that new carbs do not use iron bases and the use the same material for the base and the carb. If I use the "coolcarb", will it work the same for the carb 94?

I want to thank you all for your time in posting. This helps me a lot.

Do you have a source for more of the gaskets shown in your first post?,,,if so ,use several of them in a stack. Compress them first somewhat so as to not distort the carb base when tightening down.
just another idea.

I did a lot of heat testing on the entire fuel system on several of my old Fords in 95 to over 100 degree days. Most tests were performed on about a 25 mile run at the same speeds on the same roads to our lunch destination. This also allowed me to take temperatures as soon as we stopped for lunch and 1/2 hour to 45 minutes later with the engine sitting while we ate. I tried an aluminum/insulated carb spacer similar to the coolcarb spacer and if anything it made the carb a little hotter. The air in the area of the intake manifold is at least 135 degrees on a 95 degree day so no hot air is going to be dispersed, infact it will attract heat. I did a Google coolcarb search and found Corvette owners found it didn't provide any help on their engines. The Ford fans don't provide air over the center of the engine, the air is directed toward the fenders. If the fan came down over the top of the engine it MAY work a LITTLE. On my tests I found Bob Shewmans 1/2" thick phenolic spacer with horizontal vent holes cooled the carb, I don't remember the exact number of degrees by it was very notable and stopped the boiling after shut down. The carb problem is mostly after shut down not running down the road. The real problem is in the fuel pump, below 55 MPH when the fuel remains to long in the 135 degree pump. Above 55 MPH there is enough fuel flowing through the pump to cool it. It starts at 55 MPH and will shut the engine down in slow traffic and stop signs. This new fuel boils at 125 degrees. Bob can be contacted at gadgiteer@aol.com G.M.
 
Dear friends!

Today I finished the template for the spacer and the gasket. It was interested.

It is in auto cad and I attach in PDF to see how its look like. As I have the phenolic I will do it in CNC Router.

Today I tested the carb base and It was at 60ºC/140Fº.

I wonder how many degrees will the phenolic decrease.!

What di you think?

Looks like you've done a LOT of work to get to this point!

How thick is your phenolic? If you use it for the bowl-to-throttle section gasket, with I assume a regular gasket on each side, it will mess up the linkage that goes from the throttle to the accelerator pump and possibly the fast-idle cam's fit to the throttle screw. It depends how thick the phenolic is.
 
Hi Ross!

Actually the phenolic is (21,2 mm) almost (0.85 inch). Still I hace the phenolic without cutting. Your point is interesting, I will check the linkage then.

Thanks

Hi all
Finally I got the spacer done. I attach pics. By the way I also cut a pair of acrylic template for making gaskets. What do you think?

I will install the spacer and test how much the temperature decreases.

I came back with news.

Hi ross!

No much cold, the most of the time in winter the temp is 10ºC in some cases in cold days is about 5ºC no less.

I attach a pic of spacer installed. Tomorrow I will measure the temp after running my engine.

Before install the spacer the carb temp was 60ºC and fuel line was 55ºC. Perhaps Must I isolate the fuel line that is of plastic?

Thank for reading

Hary
