Whats it worth{should I sell it}

[RichSchmidt]

When Building the current engine in my race car I pulled an engine block out of my core bank{bottom shelf of the garageLOL} and after I looked at it I thought it might be worth something more then the average bigblock.A soon as my machine shop guy saw it he said I should sell it and I would have enough money to buy a new Dart block.I had a full rotating assembly and needed an engine NOW,so it got machined .060" over and in the car it went.I figured I would see if I really have something special.Future plans call for a 4.25" crank kit,and I have 2 more 454 blocks sitting around doing nothing,so if this thing is worth something I might just sell it when I finally pull it.

It is a 427 block with the casting # 3869942.The date on the side of the block{none on the rear} is real rough but looks like it ends in 5.THe code on the deck didnt translate into anything in any of the available code books,but if I looked through all the codes and tried to mix and match what means what,it looks like it might be a full size 1966 cop car motor.It's a 2 bolt main with the canister type oil filter and uses the grooved rear cam journal.Does anybody think this is a really sought after piece?

Thanks.
