Ok, I think have a 750 double pumper w/mech secondaries. I have looked on Holley's web site and that is what I come up with, but... The don't show a number exactly like mine, I think due to age. On the air horn it's stamped...
List 4779-2
3529

On the web site can only find a part# 0-4779C. That shows above specs, but with 4 corner idle, only have 2 in the primary metering block. Ideas???;)

To decode that:

(F) 70, primary main jet
(R) 80, secondary main jet
6.5, 6.5 primary power valve

4150, 4150 design modular Holley carb, with secondary metering block
