904 300m billet input shaft question

[Duane]

At what performance level is this shaft required in a drag car.
3100 pound 68 dart say 570 horse motor with trans brake, 10 second et.
Will the stock imputed shaft be reliable. Opinions wanted.

Thanks
Duane

I have about 1,000 pass on stock imputed shaft. The car weight 3130 and the motor making 660hp and 575tr. I launch at 3600 off the trans brake. I had no problems

I am using a 999 out of a mid 1980s diplomat or something. It was one of the lock up versions
With the low 2.74 first gear and all four pinion steel planetaries. I picked up a slant six pump and input shaft from a older non lockup model to convert the 999 to non lockup.
