Looking for any clarity on what the stampings mean on my 440 . I Know D = 1968 and of course 440= 440CID. The Maltese cross =.001 undersize crank journals I think. But the  rest of these stampings I haven't been able to figure out.I would guess the 10 10 30 means the mains and rods were cut .010 under and the cyls. .030 over but is that correct ? The 7 80 maybe when that was done ? The rest of the markings  ??? : Any ideas  ? THX !!   :notsure:



Mr Cuda

You have some non stock stamping on your id pad.
D440, so 1968 block. Maltese  cross is a factory stamp, but the machine shop that rebuilt it put .010 rod and main undersize, plus .030 piston  right on the pad. Too bad.
sac is probably the initials of the shop
