The Car I had recently bought from copart was a 2009 Granturismo 4.2. One main incentive on my purchase was having only 20888 miles. As me and my dad were trying to start the car the starter initiated but was not able to crank the engine. We removed the air box to get to the crank. As we tried turning the crank it stopped at one point. Could this be caused by the cylinder hitting the valve or could this be because of the timing belt? We began to look for replacement engines and only could find engines for the 4.7 and the Quatreportte, Could any of these engines be swapped in without any major changes? If you could in any way help a 15 year old figure this out this would be much appreciated, thanks.
