1966
Bob,
From my Atlanta Buick Library:
You Said "Engine Code Stamping: "B" ( presuming MB )"
If it is MB it denotes as an “optional” 340-4bbl for the 3600 series Special Deluxe and 4400 SportWagon.
Casting Numbers
Intake: B 1374559 P ( Four barrel square bore ) - Also for 1966 casting # 1374558.
Block: 1374557 M
Head, Driver: B 1376330 J - 1966 340
Head, Passenger: B 1376330 J
Exhaust, Driver: 137590? – Cast (should read) 1375907 1966/67 300-340
Exhaust, Passenger: 1375912 – Also 66/67 300/340
Carter shows to be a ’66 number
Transmission:
Super Turbine 400
BU - 66 – 71212 – The “BU” code usually is for the LeSabre but my notes indicate any model ordered in '66 with the 340-4bbl with an ST 400 received the “BU” trans.
A couple of 2 cents worth
