I think its 5200 RPM's on a stock 383. In the old days I did a lot of street racing with a stock 383 Dart, and shifted it at 5200 RPM redline. I know my engine would sound like it was screaming at 5200 RPM's. And I could never see any gains above that.



I was throwing that out on the engine holding up. I don’t think a 440 with a stock cam will like buzzing it up there at 6200 since a 383 with same cam wouldn’t either. My understanding was those chart were for what you could expect to get by with on a stock bottom but modded engine. Wish I could find my book.

I want my fair share
