COPO Chevelle Motor

[Ls6 Ragtop]

Just thought I should post that the original intention of my post was not to get a buzz going to try and hype the block and then put it up for sale. At this point, the only way my friend who has it would entertain parting with it is to whoever happens to own the car that it came out of and that was through a lot of nudging on my part to try and reunite a really cool motor with its original engine bay.
He has had this motor in his family since the 70's and had no intention of ever selling it. I was and still am hoping the original car still exists so this engine could get reunited with the original car. I know if I had a car that was missing it's original engine I would hope that if someone found it's original block that they would allow it to be put back where it belongs!
Thanks, Chris

With Chevelle series cars, isn't there another body style that would've had different prefix serial numbers or is 13637 the only possibility?...Joe
