5000 RPM. The 440+6 was not a high rev engine.
When Ronnie Sox drove one for Chrysler he said he was shifting (no clutch) at 5400. Air Cleaner Assembly removed, rear tires set 10 lbs lighter. 4.10 rear. He ran an ET of 12.98 after a handful of tries.
The only "high reving" stock engine that Chrysler offered was the 340 Magnum. Shift at 6000 RPM
