MO replacement?

[tims68z]

I have a 68 Z that I have owned for 20 years the car was purchased new to drag so the MO engine is long gone. I have come across some one who has owned a 68 Z for 24 years and has the long block that came in car.It has the correct STD crank,rods,pistons and heads(3917291), the block is suffix CE0810114 and the person wasn't sure about all the no.s. I assume this to be a replacement engine the cast is 3970010. My question is is there any value in having a CE engine? <font color="purple"> </font>
