Isuzu npr Truck- does the used engine have to be out of npr?

[0twinview0]

Hey Ya'll,

My 1998 NPR has the 5.7l gas motor and needs to be replaced. Im considering a used motor with around 80, 000 miles. The used motor is 5.7L gm longblock, but will any 5.7l longblock from 1998 work? Does the engine need to be a specific 5.7l for the isuzu NPR?

Thanks

I have one that has two motors, the long block is the same, it gets hit or miss from there out.
