trade gone bad...opinions?

[DBear]

Hey guys...I had a bad experience last week. I was gonna trade my 69 Burb for an '05 5.3l and 4l60e combo. When iI picked up the combo I gave this clown my title and he wanted to pick up the burb later. After being skeptical about motor combo I checked tag on ecm and it came back as an 2003 model. That made me more leary so iI pulled pan and sure enough...it is a 4.8l. I have notified the guy that we would not be completing this trade. He was putting it off on someone else. He then said he wanted to check serial # as if I was pulling a switch on him or something......with this said, I still have my burb and his motor.I just want my title back. With me still having possession of the burb, can he do anything about it?

Oh....this was a craigslist deal.

Thanks in advance
