1967 L88 Baldwin Motion Crate Motor with Doc's

[MRIROCZ]

I hope this is the correct place to be talking about this? Anyways, I am a Camaro collector that got a call the other day from a friend that said he wanted to sell me his REAL DEAL 1967 L88 Crate motor that he bought brand new from Motion Performance in 1967! He said he has the original work order paperwork, as well as the complete motor sitting in his basement! I have all the numbers off the motor to include the very rare aluminum heads intake, Motion add on's cam, pistons etc... What I want to know is what this thing is worth? It was in a car in the 70's for a short time and then taken out and put away for storage. "The motor was put away the correct way!" Any help would be greatly appreciated! J
