Not really. There was no mention of "The only way to tell" is to drop the pan. Just that it was "a last resort". Which leads people to believe (at least it lead me to believe) that there is still another way to positively ID the engine with only casting information visible on the block. Which we have now found is not accurate.

Based on the information presented here, there is no definitive way to tell a 230 from a 250 (via external casting numbers on the block) without dropping the pan and checking crank casting numbers.

Does that sound about right? If so, it will help the next guy when he finds himself in a similar situation. \:\)

I don't know any of this stuff, there is no assuming going on. ;\) I really don't know.
