Holley 3878261-EH List-3310 with a date of

[ted]

035 .... Believe Holley had 2 different ways of dating carbs.. One started in '72 with the Julian system but, prior to 1972 how was (is) one to de-code the earlier Holleys?? Metering blocks are as follows: 5271 front and rear block is 4519 .. I do not have it in front of me, but, does float bowl housing 848N in blackish ink stamping say anything to you ??
Questions are: 035 means what remembering Holleys did not do the JUlian date thing until 1972?
848N on one of the float bowls is consistent with what carb?

Thanks gentlemen!
