440 decoding guys, i need a minute

[Bulldozer]

ive searched the net everywhere , including my FSM and i cannot for the life of me find out what the 2 - maltese cross - X means on the pad. i know its the main journal size (and rod?). i know the 7T440E is 1977 trenton 440 cast crank and the 5 11 is the date code. but what is the rest? also, what is the numerical number for the standard size of the main and rod journals on a 73 and up cast crank ? and do the 2 + X represent over or under size main (and rod?) journals ? i cant find squat for info . thanks guys

The Maltese Cross and an X = 0.010 undersized crankshaft.

X = oversized valve guides.

See here for decoding, it took me 1 minute to find, LMAO.

ONE minute Bruce ?

Yup, I use Bing now, it turns up more than Google. Plus Bing doesn't put up all of those annoying ads you see here, Google pops up ads of things you have searched for.

Here is what I used.

Information on the 440:​

Question from Vincent (1967):​

I have a 1967 Imperial LeBaron with a 440. I would appreciate it if someone could tell me what the cross symbol on the identification pad means. I have only seen this once before on a 440 engine that came out of a Dodge police car.​

Reply from Rodger:​

The Maltese cross means you have a bearing that is a different size. The cross should be followed by a number ( or two ). The number(s) will be the bearing(s) that have a different size. It can happen with any factory engine.




​

I know it says the number follows the Maltese cross but it could be that 2 of the bearings are a different size than the rest OR that number 2 bearing is a different size.

I'm betting on the latter. It seems as though on some factory engines if there was some damage on the crank they would just machine it a little to "clean" it up and use a different size bearing.

Pop it apart and measure them, I'll bet that is the case.

everything im reading is saying the 2 means 2nd shift, if the 2 preceeds the cross

Like I said, could be. I didn't see that anywhere, probably ain't lookin' close enough.
