How much to change motor in 2007 cadillac cts

probably best if you call a parts house or Jasper Engines or a junk yard,because you have all the info on the car including the engine size which you didn't include here? 3.6L or 2.8L? they can help you.just don't see how the engine was ran without any oil in it? new one is probably $5000.00--$10,000.00...check with a salvage yard for a used engine,less $$$$$!

I have a 2004 cts .my timing chain went back in 2013.I replaced the motor instead of fixing the chain.they wanted $2000 for timing chain .a used engine with 70000 miles was $2600
