This is news to me, what are the torque/up limits on the 01 Cobra crank?

The cobra crank is a forged piece made by Kellogg. It is forged from 4340 steel and has center counterweight that make it a bit more stable at high RPMs.
If you are building a stock stroke motor, this is the crank to get. You would need to go into the megabuck billet crankshafts to get better than the 96-04 cobra crank in the aftermarket.

As for torque/hp limits, it is the go-to crank for 4 digit power with a stock stroke crankshaft.
