Kurt, I've got the XB3 crate engine, 345hp, $3100 from Gene Evens Ford, free shipping. You'll also need the stuff to make it work with the Mustang pulley set-up, about $200.
The M-6670-A50 kit from Ford includes dual sump oil pan and pick-up tube (not required in the cobra), dip stick & tube, crank damper, timing pointer, water pump and timing cover. You'll also need: intake, throttle body, injectors, EGR spacer (if using GT-40 intake), distributor, plug wires, headers, heater tube (if you are installing a heater) and probably more stuff I can't remember.
