Engine decode help

Ok there is a local guy selling 5 440s and 1 that he thought was a 413 but casting number says can be a 413 or 426 and the stamping on the pad is all wackey.on the stamping too me i see T 41 then below that is a faint maltese cross and below that looks like either 126 or 1126 so i assume 413 TIA

Faint maltese cross with hp sorry

What's the casting date? I'm guessing the "3" is missing from the T 413.

My thoughts also

Can't read the pic you posted above, sorry if I'm repeating what's on there.
T = 1963 41 = 413 42 = 426
I can't quite read the date either, if 126 Jan. 26 1963, if 1126 Nov. 1962. whichever it is should still have a 1962 casting date or a very early 1963.
I didn't have my coffee yet.

So what does the maltese cross mean? I've got a 413 in the shed with that marking.

gee could you draw us a picture? wow!

The diamond is the only one that screws you for oversize lifters then you have to bush the lifter bores. By the rust on that block undersize bearings are not a issue

 

[commando1]

I never even thought to measure tappet bores before this.
Then again I have never had a block stamped with a diamond...
