Holley 750 cfm 4150 HP car racing carburetor part No. 510-0-80528-1 in rebuilt condition.
Full specs are here:
Holley 0-80528-1 Holley 4150 Classic HP Carburetors | Summit Racing
This was used with a Roush 427R (351 Windsor dart block) motor in a Superformance Cobra.
I rebuilt the carburetor using the AED Ultimate rebuild gasket kit, which includes the superior blue bowl gaskets for easy jet changes (and they can be reused a few times). Rebuild was done November 2020, and included an ultrasonic bath cleaning for the reused parts.
Longer vent tubes were also installed to prevent splash over during hard cornering or braking.
After the rebuild was complete, I tested it by running it on the car for a whole day- it runs well with no issues. The original gaskets were in good shape and the carburetor was pretty clean internally, but I wanted a fresh rebuild if I was going to store it as a spare.
Current Jetting:
Air bleeds: 76 36 36 76
Power Valve 6.5
Main Jets:
71 Primary (x2)
80 Secondary (x2)
Accelerator pumps 31
Green Diaphragms
Metering blocks:
11180 Primary
11038 Secondary
This was run on a street car.
Ships in a reinforced AED box. Includes a used carb gasket which should still be functional. End user should expect to reset the four corner idle adjustment and idle screws to suit the new car. Float height is set, but I would re check it anyways.
