So I went back and read this thread again because I didn't really understand why he got so butthurt last night.
I take 2 things away from this.
1) he didnt get scammed or ripped off he received the engine at the price they agreed upon! The only thing he didnt receive is a cam card! I would be upset if I paid 15 grand and didnt get a cam card but I wouldn't consider it a scam as a matter of fact I dont see anywhere in the description of the add where it says a cam card is included.
2) the OP jumped the gun on calling the ppl who was trying to help him out assholes lol
3) you stated that you gavent even started the engine yet so how are you gonna leave negative feedback and rip this company over a product you haven't even tried?? Because of you didn't receive a cam card??
