Thanks everyone for their help.
Both motors were received in a trade. Both already had dyno stickers on them so I am not sure how the figures were calculated.
The Stampede project is just a factory Pede with FLM extended alum front a-arms, 5x11 carriers, GPM Alum threaded shocks, MAXXimizer wheel adaptors, TMAXX offset wheels/tires.
I dont need it to be super fast, but good speed and lots of torque for the bigger wheels. I am leaning towards a Novak GTB 5.5 brushless (someday).
Until then, I was hoping either a 15T or the P2K would do the trick. I guess it's up to gearing mostly.
Thank you again for your help, hope this makes a little more sense
