A stroker crank does not make more torque, the torque is simply a displacement function more equals more, less equals less; PERIOD! The only thing diddling the bore to storke relationship does within a fixed displacement is move the RPM around where the peak occurs, not the amount. Longer stroke lowers the max RPM where the peak occurs, shorter raises that point. For an otherwise idential configuration of parts that's all that's happening.
The torque number might be a little higher in a identical engine size comparison.
Your point is alright for me. The 3.73 gear can be got cheap online.
