We have a local guy who advertises built bbc engines in the paper all the time. Man I know bought one to put in his TransAm, turned out the engine was put together with all junk, mismatched parts. He ended up suing the guy and did get his money back, but it was a fight.

I am in the marine business, and I see work done by other marinas and mobile techs all the time that borders on fraud. Anyone can get a business license, a listing in the phone book, and a shop. However, only a certain percentage of those are qualified or honest business people. That extends to the car hobby as well.

If you have any documentation of what you were supposed to have in that car, I would consider Small Claims Court. It will only cost you a few bucks and generally the burdon falls on the business to have superior knowledge, and the courts view it that way. If you only have a verbal on the 330 HP thing, you probably are out of luck, but it still may be worth your while to inconvenience the guy for the day he has to go to court, and it may also shake him up enough to make him want to make it right.

JMO,
