Personally I'd be ticked off. Unfortunately what we don't know is if there was some kind of indication from the seller that the engine had been gutted. I'll be honest I had to skip through the video so this might have been mentioned either way.
That being said I would have been a bit more careful and been better at examining what I was purchasing but that comes from experience. I would definitely contact the folks running the show. I'm fortunate to have never been a victim of this but I wouldn't let them off the hook so easy and would pursue this further. Someone knows who they are, especially the show operators. Let's see what their side of the story is but this should be pursued.
He does mention that the guys didn't take Credit Cards and that should have been a red flag. I completely disagree with that. I don't take CCs, only cash at shows. What I do have is a test track right at my table. You don't have to go anywhere to test what I am selling. Me and the guys I go with all test everything for you before you buy it if you want. If it doesn't perform as expected you can offer me a lower price or you can walk away. Gives the buyer and myself a piece of mind. I've even tested other purchases but I tend to avoid that so I can't be blamed for an issue that might be present.
