Chrysler V8 recommended max rpm

[Barrie]

To my way of thinking the idea of piston melt is theoretical. I have never heard of a case on road engines. What would concern me more is that, over a period of time, oil may not return fully to the sump and build up in the upper part of the engine eventually starving the sump and causing bearing failure. A warning of this would come by falling oil pressure. On long fast runs on my 440 engine the oil pressure falls but then stabilises. I rely on the oil pressure gauge.
3000 rpm on the Torqflite gearbox is 3 x 26.5mph per thousand rpm so, say, 80 mph. I would have thought that’s easily achievable as would 4000 rpm (110 mph) the difficulty is finding roads open enough to do that continuously even in Germany.
