Title: What do these numbers mean?
Post by: sixt9x33rs on August 09, 2010, 02:35:35 AM
I saw these numbers on the back of a small block with the bellhousing removed. They were above the crank:

678636 386371 H35
371386

The H35 is not a casting date. The casting date was in the normal location.

Thanks

Those are foundry identifiers for the various patterns and cores used to form the sand mold for the block; they're unrelated to the final assembled configuration of the engine.
