NOOOO!!!

do not buy a 5.7L(350) GM diesel. one of the worst engines ever made. ask anyone who has ever owned one, (my dad) you cant keep head gaskets on the engine, not to mention everything else. everyone my dad talked to said the same thing, they were just plauged with problems and everyone just swapped them out for gas V8's.

the 6.5's are good engines but parts are rare and kinda pricey.
