Re: IML: is a 440 a 440?

["Melissa Swenson" <emswenson@xxxxxxx>]

Good evening fellow Imperialists.
I realize I may be a little late to jump in on this thread but I may be able 
to clear up a little confusion on casting numbers. These types of things can 
keep a guy or gal up at night!
Good news, it's a 440! The number that the mechanic was referring to is, 
quite appropriately, is the block casting number. ALL 440's '66-'72 had the 
same casting numbers-2536430. This refers to the block only. It also has 
nothing to do with displacement. For the record, '73-'78 440 blocks are 
numbered 3698830-440-  now with the displacement following the casting 
number on the side of the block. Also cast into the side of the block is the 
month and year the block was cast. On the pad under the A/C compressor 
usually stamped is the displacement, in your case B440, a date, and maybe a 
symbol or two regarding casting screw-ups and now having undersize bearings 
as a result. VIN numbers were not added to blocks until the '68 model year. 
Another tidbit- sure while I'm at it. ALL 413 blocks '59-'65; 2205697.
I am pretty sure your '66 has the original engine. Check your intake 
manifold number on the runner just ahead of the carb-2206000. Or your carb, 
Carter AFB #4131S or #4137S with clean air package. Sleep well my friend!
