So I sold the 400 but was able to keep the carb. Just for fun I looked up the carb number and it's from a 1978 Chevy truck with a 400 or big block. Perfect, that's what t came off of. Then I decided to check the Q-jet that was on the 350 I put in.
70 - Rochester Quadrajet
2 - 1960's
9 - 1969
2 - 4bbl Federal Standards
0 - Chevrolet
4 - Auto Trans
So I did more digging and came up with this.
Now for the date code. I've read that it's either under the part number (I've read this is '69 through '74), or on the baseplate near the driver's side rear bolt. Early Q-jets had a 2 digit code on the tag while some '68 and early '69 had a 4 digit Julian code. Mine has 3 digits. Do you think it's a replacement? Or did they leave the 0 off and it should read 0129? So the 12th day of 1969.
