Default Holley 4555 3972121 LT-1 & Z28

SOLD
I have a near new Holley 4555, 3972121 780cfm carburetor. This is a recently manufactured carburetor, made by Holley, for the 1970 LT-1 and Z28. It can also be used on the '71 and '72 solid lifter 350 cars. I had this on my '70 LT-1 car for about 200mi until I rebuilt the original carb. It is still in new condition. I used mostly ethanol free 91 octane and drained it completely when removed. Never tampered with or taken apart. I only adjusted the idle screw and fuel mixture slightly as it ran great right out of the box. As you see, it is stamped 4555 and 3972121, but has no date stamp. Plating and color exactly as when new. As you see it includes the original box, unopened literature, tags and also has the packing bag etc.
Here is how Holley describes it:
New correct design Holley carb for your Corvette or Camaro. Exact for all 70 small black LT-1, Z28 and 350 high performance models. 780 cfm delivers the needed fuel to give optimum response to your ride. Features original GM part number 3972121 and Holley list number 4555 on the front air horn, just like originals. This is a brand new in the box Holley carb. Gold iradite plating as factory units. Correct for automatic and four speed transmissions. Fresh to date technology with the right old school look. Tested and guaranteed, ready to rock!
Exact fit for all 70 Z28 ~ Automatic and Four Speed Transmissions
