Nema 34 stepper motors?
(OP)
Does anyone know if there is a Nema 34 frame size stepper motor out there that will handle 240 ozin of holding torque at 5000 steps/sec? I have been trying to find out with no luck. Any help would be greatly appreciated. Thank you.

Check out this site;

and check out the "What's New" and "Products" link. This guy commonly stocks NEMA34 steppers with toruqe range well above what your requirements are.
Assuming 200 steps/rev, 5000 steps/sec is 25revs/sec X 60 = 1500 RPM. That's a pretty nice RPM for a stepper. I believe it can be done but your choice of pulse source, drive and power supply will be crucial. What is your application? Tell me more about how you plan to drive the stepper(s).

Can I ask what you are using as a pulse source and as a stepper drive? Check out;

The G201 is a 10x micro stepping drive, the G210 is also, but adjustable for full step, half step, micro step etc... They will drive a bipolar stepper up to 80V and 7A/phase. They accept a digital step and direction signal. Your power supply should be more than ample, and with a fast pulse source you should be able to achieve your speed goal.
