Decoding my Q-Jet
generally i know how to decode stuff, but one number has got me confused on this one. Can some Q-jet Gurus chime in?
As i read it.
1708 1282
2730 DKD
Top to Bottom, left to right;
1708---> Later series 1980s
1----> Year produced, in this case 1= 1981
2 ---> Quadrajet (4 bbl) Federal standards
8 ----> ??????? I thought it may be a 3, for cadillac, but i posted a pic, judge for yourself.
2----> EVEN NUMBER meaning Auto Trans.
273 ---> 273rd day of the year
0---> Year
DKD---> Production Plant Code

According to http://www.carburetion.com/Number/bynumber.asp :
81-86 Chev/GMC/Truck OP 64-7160
Probably a 1981 model year carb manufactured in 1980.
