It definately was not drop in, the intake manifold was a little different as well as vacumn lines and the EGR valve(no line running to exhausr manifold.). It was not a bad install, although it is the hardest engine I have ever personally swapped. As far as being more powerful, I have only driven my SVX no others, but it seems quite a bit quicker. The business I bought my motor from was a place called CNS motors. Andy is pretty nice and told me that they were going to possibly be getting entire front clips with engine and tranny's. However I have not talked to him since purchasing my engine. Here is the Link
