454 4 blt needing sleeve worth $200???

Hey guys, I just saw this on CL;
"This is a nice 454 4 bolt main block, standard bore, 1 cylinder will need to be sleeved, great big block to build."
He wants $200 for it. I am going to build a 496 stroker. Is this worth a look? If so is there anything I should look for or ask?

Thanks
Wade

i put sleeves in all the time .if done right the block will be fine. i know how to put sleeves in right but there is many shops out there that do bad work the bottom of the bore must be solid if not the block could be junk
