The engine in my 1969 GT350 is a 1975 date code block with early 1969 date code heads, carburetor, and distributor. The vehicle was assembled in late December 1968. Upon inspection of various original date coded parts, I've found them to range from late 8J to very early 8M, with the majority in the early to middle 8K timeframe. That being said, what would be the most likely date code range for the engine block and other date coded engine components?

After reading your post it seems like you have kind of answered your own question. The 8J to earlier 8M time frame is a reasonable guide line with a early 8M closer to ideal. Just my opinion.
