:disappoin I'm looking to buy a Northstar out of a 1994 Deville and put it in a 1994 STS. What parts will I need to swap from my old engine to the one I'm getting from the salvage yard. I saw something about the cams being the only thing that is different on the two engines...is that true? The Deville is a Vin Y and my STS is a Vin 9. I'm hoping it's do-able since I found this engine for $700 and everywhere else I've looked they are at least 2 grand.
