I hate to part with them but my idiot builder only built my house with 5 garage spaces instead of 6. Plus, I was supposed to have more storage area. And, Yenko didn't save the old engines, so if this comes back to bite me in the butt just remember not too long ago I sold a '66 Paxton SC Mustang Shelby, CA car, low mileage and no rust for $17,500.
So, I've done stupider!
I'm posting something similar on LS1Tech trying to get an idea of what it's worth. Seems like somebody could use it.
