Back in the day I had a 70 Road Runner with a small block installed. Hemi 4 speed, 3:23 Sure Grip with L 60 15 tires and traction bars. 1st gear, clutch engaged, throttle wide open, would break the tires loose when the cam started pulling, for about a month with a new clutch, until the clutch would start to slip. The clutch was pretty much junk in about 3 months. Sure was fun while it lasted! Definitely nothing stock in that setup.

A stock 383 motor? In a drag car? I wouldn't expect it, but a few might surprise you. Some were definitely stronger then others. I beat on a lot of 383 Mopars in those days, if they hung around long, they didn't stay stock.
