there is a topic on this on ths site,, this is not impossible by any stretch or the imagination,,you may have to kmomve the steering column over a 1/2 inch,but thats easy,,the valve covers are very close to the iner fender wellas at the shock towers,,,minor modifacations,,,
and yes catch your drift,, on warrantry hemis,,seems to be a lot of them dropping valves,,,i see them on craigs list here all time, same mechanic,, selling short blocks,, etc,,out the back door of a dealership,,,lol
even had a guy in detroit with a 5.7 zero miles,,,selling it,, you know that went out the back door of a dealer ship or the factory,, tons of 5.7 hemis around to be had
