Ok so I came up with stamped in the back of the block M226 where the date code shows in your picture
i could not find any other number
the heads are stamped GM-1 ? Any info
So looking online is this a December 22 1966 engine? Going off M226
I’m trying to figure out this engine number
I was told it’s a 73 Pontiac 400 engine but having hard time decoding it
this is the number on the passenger side front engine block right below the head
282108 YE
If there’s anything else I can look at just let me know
