Did they have to put any heavy metal in the crank when it was balanced ?

I don't recall that. Current shift point is 5200rpm. Also running a Hughes street/strip, 2400 converter, GV overdrive and 4.11 traction lock.

216 @ .050 doesn't seem like a lot of duration in a 400 engine but a few years ago I had a 375 inch Cleveland with a factory intake, Boss 302 heads and a hydraulic roller cam with 212 at .050. Even with that short of duration it still power peaked at 6000 rpm.
