I had the block decked,so the code isnt there.It was something like IP IE or something like that.Its still in the car and being raced,but I wondered if this was a real rare piece or not.Thanks.

as stated above, there are a LOT of Corvette people looking for a block like this (before it was decked and bored) and apparently paying good money too

IMHO AFTER you decked the block is not the time to ask if it is worth anything, as the bore AND decking has diminished its worth

the engine shop guy told you it was BEFORE you did that, I am surprised that he didn't tell you to bring in one of your other blocks ... or talk you out of it UNTIL you found out what it was worth
