Dang, Block was made Sept. 3 1968, question is, was it out of a late '68 or an early '69?
BB was used on 230 in '68, and switched to 250 in '69. Looks like Twisted6 idea of looking at the top of the pistons is going to help clinch this one. Otherwise dropping the pan and checking the casting number of the crank would work also.
