Inadvertently exceeded driveshaft "Critical Speed" at Willow Springs.

Are you able to redline in top gear?

I don't know if it will. With the current cam (214 @ .050 w/ 110 lobe separation) should be 410+hp. I would definitely need a longer run than I had at Willow Springs to do it. But, it was pulling hard at 130+ mph, so it seemed that it would eventually redline in 4th.

I'm upsizing the cam (234 @ .050 w/ 108 lobe separation)to better match my intended use. It will bump the power up to 510+hp, and make it easier to potentially approach redline in 4th.

It only has to rev to 4690 rpm in 4th to make the drive shaft hit critical speed now.
