Jerry, Royce is right about the block. It looks like I spelled "possibly" wrong, in fact it looks almost exactly like "probably". All of the subsequent discussion about measuring and checking was to help you get a better idea of what the block was actually cast as. You can bore just about any 390 block to 4.13, but they may be too thin to last. In fact, you just might hit water, especially with a rusted 30 year old block. The problem with any block you don’t know the history on is that it could be just about anything (with the exception of the 427s, as Royce noted).
By the way, both Royce and I forgot to say “sonic check”. Even if it does have the 428 in the water jacket and the C on the back of the block and passes Shoe’s drill bit test, have it sonic checked before you bore it. In fact, it would be good peace of mind even if you don’t need to bore it.
