So is 378 lb a good bench press?
If that lift is a bench press, 378 lb (171 kg) puts a man at 82.5–87.5 kg bodyweight at the 95th percentile of 29,914 judged competition benches — world-class. For a squat or a deadlift the same weight ranks lower, because those lifts are heavier for everyone.

335 lb × 4 — common questions
What is my one-rep max if I lift 335 lb for 4 reps?
About 378 lb (171 kg), taken as the mean of the Epley, Brzycki, Lombardi, O'Conner and Mayhew formulas. Individually they give 365 to 390 lb, so the range is the honest answer.
Is 378 lb a good bench press?
If the lift is a bench press, 378 lb (171 kg) puts a man at 82.5–87.5 kg bodyweight at the 95th percentile of 29,914 judged competition benches — world-class. That population all competed, so it is stronger than a gym average.
What should I warm up with?
The ramp below runs 151 lb × 5, 208 lb × 5, 264 lb × 3, 302 lb × 2, 340 lb × 1, then the working single at 378 lb. It is a conventional ladder rather than a rule; the test is that the last warm-up still moves fast.
