supposed to be a Gen 5 BBC, the stamped numbers on the pad look to be.
G083 1014182

Do we need the casting numbers from lower on the block? Any help is appreciated!

Could it be a 10114182? If so, it is a Gen V 454, 4 bolt 1991 (or later). Hope that helps..

Thanks Glenn, it’s believed to be a Gen 5. 454. I’ll see if I can snap some pics of the stamped and cast numbers and post them here. Maybe we can define the year and model

Is it going into a build, or making a trip to NM?

Neither, it’s in a friend’s hot rod and we’re curious
