Did a quick measure and journal bore is 2.085". From a quick google search that looks to be same as the OEM cobra crank. Not sure on the rod length w stock stroke crank. Might give MMR a call on that one to check.
Edit: guessing they aren't the same length b/c the 'stroker' rod is more $$ than the standard rod they sell. I'd still suggest giving them a call to verify tho
