Technical Mystery Holley ?

Hi, I have this Holley Carb. for about forty years. I had it on my Corvette for a while back in the 80s i guess. Well I can't remember what CFM it is. The base primary and secondaries are 1-1/2" .
Base plate # is 11294 and the air horn # is 6R-7809. Thank you for you help.

 

I think that's a mid 1970's Holley made for Ford.

 

The above chart may help, you can check the venturi sizes and that should provide a positive ID. The 1848 has primary and secondary venturi’s the same size.

 

I remember rebuilding one for a buddy of mine.... I think it's an L-79 327-350 hp carb.... I could be wrong.... We need pictures of it....

 

The bace plate

Hi FORDORS the base plate primaries and secondaries are 1 1/2 in diameter.

 

I am trying in identify the Carb. Not the car. Thanks for looking. Jim T.

 

Post a pic.

Vac secondary? Double pumper? 4150 or 4160?

With or without choke horn

The 6R is an old generic HP series main body casting mark

 

Yes, that's why I mentioned checking the venturi diameters, the 1848 and 1849 both have 1 1/2” throttle plates, you want to compare the venturi sizes, if you have an 1849 the secondary will be marginally (only 1/16") larger.
Have you looked for the list number stamped on the choke horn? It would be on the right front of the choke horn and be stamped LIST 1849 for example. It sounds as though there is no choke horn on your carb, is that correct?

 

I am trying to identify the Carb. I will post pictures tomorrow. Thanks Jim T.

Now that you know what car it came from, you might be able to go to the appropriate service manual and get the info you REALLY want.
