If you didn't build the engine, how do you know it's been built properly?

Ignore everything that's been done and go back to basic diagnostics even it if means having the partially strip down the engine to check things. If the customer doesn't like that, tell them to take the engine and get it on a dyno to show that it runs properly first.

Just because someone else assembled the engine doesn't mean it's going to run properly.

Can you define "completely redone?" Did that list of "everything" include heads, valves, cam, timing set, intake, injectors, distributor, crank, re-decking, or what?

If the injectors were changed, what flow rate are they? What is standing fuel pressure? Where is the base timing set?

The more information we get, the better the guesses.
