Thanks !

Note, the 7029200 EE is missing the "70" on the carb.

The Digits are stamped not cast as in the 4-speed carb.

Car was assembled in February so a December 68 date for the carb is possible.

Does this mean 0751 is 75th day of 1971 on the four speed carb ?

Had a stressful day at work so I took my broken arm out and did automotive stretching exercises.

Swapped the carb and after I corrected the stubborn fuel leak, took her for a spin

   Holy Mother of insanity !!!

The last time my gut sank into the back of a seat like that was in Mark's 67 Grande (496)

I ended up all grubby at the local cruize night because my neighbours were there.

On the way home, I did a dead stop on a country road and let it go.

11s all the way until the back started to break loose.

Did not test the limits of the car.

Happily cruised home at posted speed.

No stalling, backfiring or rough idle.

Bill has done an amazing job with this carb and now has another one to build.

Right after he finishes my M-20 

Holy Mother of insanity !!!

A better carb, or one thats tuned will always cause this to be yelled out. It's happened to all of us at one time.

AGREED!!

regarding the carb stamping, Rochester revised how it stamped numbers for the 1969 model year from what it dod for 1968, then revised it  again during the model year.

But I need to push pause, because something seems fishy about that m/t carb.

Rochester used a four digit dating system;
XXXY
XXX = the numeric day of the year
Y = the final digit of the calendar year

Now, this is the clincher;
The two letter 'pick code' was only used for carburetors manufactured during a window of time where they might be sent to the vehicle production floor;
After the carburetor was no longer used during production, the pick code disappeared.

ok;
Back to the two carbs:

a) 1966 through to VERY early 1968 Quadrajets used a stamped disc that was attached to the fuel bowl;
b) most 1968 Quadrajets only had the application code and pick code stamped on the fuel bowl - the date code was stamped on the throttle body; this stamping on the fuel bowl only used a single line stamp.
c) early (and most) 1969 model year Quadrajets had the application code stamped like the 1968 units, in that it used a single line stamp; unlike the 1968 stamping, the first two digits for the application code were dropped and the pick code immediately followed the application code. There was a single space, and a four digit date code stamped after the pick code.
d) late in the 1969 model year, the stamping was revised to now take two lines; the full application code came back, with a double space between the application code and the pick code; the second line now had the date code.

Your (70)29200 carb looks 100% legit, the stamping is uniform, and nothing seems out of place;
That carb was manufactured on Thursday November 26th 1968.
(The 1969 model year would have been September 1968 through to July 1969)

Your 7029201 carb looks to be restamped;
The "7" is double stamped - I believe that the way these were stamped, this wasn't possible.
The stamping is not uniform - notice how it gets more defined at the end(?)
The assembly date is wholly wrong for a carb with a pick code;
That date (0751) is for March 16, 1971.
A 1969 model year carburetor manufactured in 1971 should absolutely NOT have a pick code.

I hope this helps.

It's relly too bad that there are some in our hobby that do stuff like restamping to make a buck... 

The "7029201" carb is the one that Howard supplied for the 2+2.

It's definitely a cast code and definitely a 1971 carb.

When it was rebuilt by Bill, he commented that he believed it had never been apart before.
