What is the difference in str's for the stalls? How can each str affect the streetabilty?

 

STR is how much the engines torque is multiplied at the stall rating. My stall has a 2.5 STR so supposedly it multiplies the engines torque 2.5 times at 2800rpm(the rated stall speed). As far as streetability I'm not aware of any issues related with STR.
