If one buys a "350" that had the engine replaced 55,000 miles ago with a MB factory engine , what if anything, could be done with MBUSA regarding reliability if the engine dies

Short block replacement has a 12 month unlimited mileage warranty...long block replacement(as mine was) give you another 4 year 50 warranty just like the car was new
If the engine work was done by a dealer you might get some assitance after the warranty period by MB...but I would not count on it.
I have been told they they have NEVER had an engine issue again with an engine that was installed at the MB dealer
I think one of the kickers here is that it seems they they kept replacing/updating parts on this engine...so the engine that was replaced in 1996 might have had a serious update from one that was replaced even a year later.
The tech who installed my engine said there were several differences in the new long block and the one he was pulling out.A very much different cylinder head for one thing and the engine shock design and assembly
As for the increased torgue of the 3.5 liter..I need it since I am driving a 140 vehicle
