Default Casting I.D. Nos. Interpretation


J-Bird's engine block was de-coded over at THE MEL ENGINE FORUM

( )

and I will post it here also for anyone interested;


You gave the following Casting I.D. Nos. from your block either here or at LCOC.


43532 ER

4-7B01 is the actual date code (CASTING)

This is the info given in the 1958 LINC-MERC TSB No. 8

4 is the Engine Plant Code (Lima)
7 is the Year Code (1957)
B is the Month Code (DEC)
O is the Day Code (14)
1 is the Plant Inspector Code

So you have 14 DEC 1957. It is an early one and explains the 7 character PN (5750416)

I have to find the interpretation of the Date Code on the bell.

OK...The 60 bell has a Casting I.D. of COMP 7976-B. Yours has a Casting I.D. of P3B 7976-B (if I read it correctly from the photo) and a Casting Date of 8AN (which I am not sure as to how to decipher the month and day). P (on prefix P3B) refers to Powertrain and is formatted differently from the later transmission parts. So this definitely makes it early).

What is the build date on the car?

(24 DEC 1958)
