Early 318 blocks

Happy New Year to all,

First I wish to state I am aware that the only true way to check bore thickness is through sonic testing.

I have come across a complete 318 LA engine with a build date of Feb 14, 1969. The engine is carb to pan complete and is $200. Ive heard the early 318 blocks are known to be able to go to a 4" bore, sometimes even more.

I would be only picking up to tuck under work bench for some future project. Is this something worth picking up, what experiences have folks had with early blocks? Casting number is 318-9. Thanks everyone.
