Turkey Pan Installation Tips
 

Hi Guys:
In one of the many crates of spare parts that came with my ERA Cobra, is a polished aluminum Turkey Pan. I have a Holley 750 4150 Double Pumper with mechanical secondaries and without a choke. A fuel log with dual hoses feeds the front and back reservoirs of the carb.

I was thinking of installing the turkey pan. What is the procedure for this?

Obviously I have to detach the throttle linkage and fuel lines.

I am more concerned about the gasketing both below and the above the Holley.

How many gaskets would you use?
Are the both the same gaskets? (four hole or 1 hole?)
Is a sealer or adhesive used or not?
What is the torque on the four Carb Bolts?

Any and all input on this process would be greatly appreciated.

Thanks in Advance.

I have same carb , You may want to put the carb in the pan , make sure the moving parts
have clearence . (Dremal tool with cut off wheel works good ).
The fuel log I am not sure about . May work out .
I used a 9" k+N with the 9" k+N extream top . I Had to modify the base to keep
clearence for hood , as the 9' air cleaner came with a base that was too tall .

I second what John 550 said. I had to do quite a bit of trimming before I installed mine (but I run a Demon - the pan looked like it was intended for a Holley). Then once I installed it, I had to take it back off and open up the throttle rod hole a bit. It looked like it had enough clearance until I'd "get on it" a bit and the motor would torque over and cause the turkey pan to rub on the throttle rod. Obviously that's a condition you don't want.

Chaplin, Chris and John:
Thanks so much for your input and experiences. I do really appreciate it.

The Turkey Pan in question was once on my car for a period of years (like the first three) according to the log book. The previous owner said he had slow speed driveability problems like "bog" which totally disappeared when the turkey pan was removed. He told me that it could have been caused either by restriction or a vacuum leak at the bottom of the carb if the pan was not right. I have got to inspect the base of the pan to make sure it is nice and flat.

In any case, the pan has been off the car for about 9 years now. I hope the clearances and holes in the pan are all correct for the way the carb is set up today. (Fingers crossed).

So, the two single hole gasket is what is needed. I see that Mr. Gasket makes them and they are an inexpensive item.

I do have a custom fabricated air filter bracket or holder that fits the double pumper and has an minute angle to it for a 9" filter. this has been on the Cobra all along and working well.

Also in the spare part boxes are at least 3 different types of chrome air filter tops and exterior screens and filter assemblies. One of these has the Holman Moody sticker on it so it could be the real thing. I also have found an odd array of carburator spaces in all thicknesses and materials (even one or two in WOOD of all thing). There is a note on the outside of the box that says "most will not work on the Cobra as they will raise the carb too high for the air scoop".

The turkey pan is a nice smooth ally, which probably could use a few passes on the buffing wheel and then a hand polishing with Wenol.

I will take some pictures, before and after should I put the pan on. Probably, after I do the install, I would bring the car to Danbury Competition Engines and have them chasis dyno the car and dial in the carb. I bet they will hate working on the carb with the turkey pan on.??

Adjusting the carb after the turkey pan has been installed is a royal pain in the you know what. I've seen some turkey pans that have 4 holes in the front and the rear allowing you to access the float bowl screws. Mine doesn't have that but I sometimes wish it did.

Yah Chris, I did figure as much. I will have to check and see if the pan has access holes and I think if it does not I shall drill some adjustment access holes and figure out how to gromet them closed, Perhaps threaded then closed up with something nice.

Thanks for that tip Chris..
