1970 Hemi 426 block VIN pad stamps

[Cuda Cody]

Need some help from the Hemi experts.  Does this look like a 1970 over the counter block?  Has anyone seen the F426 stamped on an over the counter block before?  @ScottSmith_Harms  @6bblgt  @cudaized   My other 2 blank VIN pad Hemi's do not have the F426 stamped on them, but they were both cast in the middle of 1969 and this one was cast in January of 1970.  Any thoughts?

I can not help. Sorry.

Never seen that. My guess would be that it was added. If so by someone unfamiliar with the year/letter stamping on hemi engines ending in the 60's.

Scott has seen alot of blocks so I'd go with his comment. 

Also, wasn't that January cast date used for alot of warranty blocks?  @Cuda Cody can you take a full side pic of right side?
