Safe RPM for a 408" Magnum?

jbc426 - Your new cam specs are similar to the Mopar 380-horse 360 crate motor cam specs: 230/234 @ .050 on a 108 centerline. But you've got more lift.
How are you controlling the lockup feature on your new 200-4R. What type of switch and where did you mount it?
I hope to finally get my trans in soon.
