after the first 300 miles the engine blew apart they sent me another engine. and it's a good thing we took it apart looked at the first off the pushrods was bent all but one. the whole thing need to be rebuilt so if I don't know if this new company bought out them and still using the same people. but my suggestion is there a bunch of Thieves and Liars. they put 300 horsepower. injectors in the motor that was supposed to be a 525 on the n14 Cummins. and that's when it was Blake benefactors hopefully they change the company.
