"The ad is saying that it's built in Dec. 68 which makes it a 69 engine. Maybe he revised the ad."
I thought that the 321 block would put it as a late 67 early 68 date.
That T0219IT to me would put it as a February 68 ASSEMBLY date.
Looks to me that the BLOCK casting date code, which is rather difficult to read, shows as eithe I-26-7 or I-30-7.
