I just purchased a pulled 6.2L military engine supposedly from a Hummer and would have anywhere between 10K-40K miles.
The Block has 660 in the valley.
The Block has M031 stamped on the right hand rear top side.
The Heads have two different Letter Number combinations. Both heads have 567. One Head has K141 while the other Head has D292.
Any feed back would be great. Hopefully it will be good feedback!!:)
Thanks.
