So is 364 lb a good bench press?
If that lift is a bench press, 364 lb (165 kg) puts a man at 82.5–87.5 kg bodyweight at the 92nd percentile of 29,914 judged competition benches — elite. For a squat or a deadlift the same weight ranks lower, because those lifts are heavier for everyone.

315 lb × 5 — common questions
What is my one-rep max if I lift 315 lb for 5 reps?
About 364 lb (165 kg), taken as the mean of the Epley, Brzycki, Lombardi, O'Conner and Mayhew formulas. Individually they give 354 to 375 lb, so the range is the honest answer.
Is 364 lb a good bench press?
If the lift is a bench press, 364 lb (165 kg) puts a man at 82.5–87.5 kg bodyweight at the 92nd percentile of 29,914 judged competition benches — elite. That population all competed, so it is stronger than a gym average.
What should I warm up with?
The ramp below runs 146 lb × 5, 200 lb × 5, 255 lb × 3, 291 lb × 2, 328 lb × 1, then the working single at 364 lb. It is a conventional ladder rather than a rule; the test is that the last warm-up still moves fast.
