I recently traded some equipment (1500 worth) for some work on my car, and I think the guy is trying to screw me...He claims he bored and stroked the engine, put a racing cam in, a new flywheel, new injectors, new cylinder heads, changed my oil(its still black though), and installed a diablo chip(Installed on the side with my fuses, my computer is on the passenger side). He did all this starting at 12:00 in the afternoon saturday and it was done by 2 am the next morning. The bore and stroke only took 2 and a half hours, I know this because it was assembled and i test drove the car then. I didn't notice any change in sound, or the way it drives. I didn't get to see any of the work done, so I doubt he even disassembled the engine. Is there any way I can easily check to see if this is legit? I really doubt it is..
