Decoding/Numbers / 3970010 engine decode help
« on: September 11, 2018, 02:18:23 AM »
I acquired what I was told was a 1969 350 that was taken out of a 1956 Chevy Belair in good running condition to be replaced with a 383 and 5 speed.
Casting number - clearly 3979910
I'm having trouble making out the casting date to confirm what this engine was when it left the factory.
There are several groups of number on the passenger side of the block, but not in a format I thought I would see based on some of the documentation I read online.
One group appears to be 6 D 8
What appears to be a clock, pointing at 3 o'clock
A1
DN
Stamping on front deck is hard to make out, seems like: K04 09 FXD
