Hesco tag decoding

[cj777]

My new to me jeep has a hesco tag attached to the block. I'm guessing this means the 4.0 was rebuilt by hesco at some point. Does anyone know how to decode this to determine if it's a stock rebuild, etc?

Looks like their internal nomenclature. I'd say just give them a call or email.

It's probably 4 steps oversize on the bore (could be 0.040" or something entirely different) and 1 step oversize on the bearings. But honestly I hate when companies do this. You don't need a code for that, just put the actual number.
