    The 512 was the casting number of the LS-6 blocks but not the number on the pad...I have 2 512's one has been decked(can't read the pad on passenger side) the other was an ls5 and if memory serves it has CRT . Any old Chilton book will tell you , let me go do some looking and I'll post it.

    CE

    I have a similar engine in my garage on the stand. The original number is still on it and is "Xed" out. It is still legible and translates to a 64 corvette hipo 327. The CE is just documentation that the original was a factory warranty and the engine was replaced. The original was then rebuilt and sold as a replacement crate engine. It is probably a great engine that you have as they probably got it right the second time around.
