Hi Eric....thanks so much for all the extra info. I stopped by the shop today to talk with the mechanic and see how he was doing with all the things I am having done on the car (wheel bearings/universals/front brake shoes/tranny pan-gasket/front alignment sleeves/etc) ....the car is suposed to be ready Monday (maybe) so I'm going to check again then and when I make sure it was also alligned I'll let the mechanic know about the casting numbers for the '66-'72 Imperials and see what he has to say then! He was SOOOOOO sure that the numbers he was showing me were the displacement! I really appreciate all your info and all the comments & data from the other Iml members!! Thanks everyone!

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!
