Hmmm... Would need to verify but I think the ' 64 to ' 67 would be the same ( except for high & low compression). Not sure about 68 & 69 model years.

Im thinking your right Winston. Id be bldg a 67 block.. I would have to measure block to make sure its std bore. Im def interested but our ppst offices might kill it. I cleaned my inbox lol
