I am looking at a Rochester carburetor (for a buddies 06C 69 Chevelle) with a date code 2649... is this a Sept 1969 or a Sept 1968 carb? I guess what I want to know is
1) Does the year code reflect the model year or the actual year?
2) Did the Julian date start on Jan 1 or on August 1 for the production cycle? I am assuming Jan 1 for what I have read but would like some facts if there's any to support it.
Thanks and this site is great!!!
The newbie.... Oh be one ;-D

1. For carbs, it's "actual" year so yours was assembled on the 264th day of 1969 (or 1979 if it's a service replacement.)
2. Julian dates stared on Jan 1 (001) and ran to Dec 31 (365 or 366 if it's a leap year).
