The strokers make peak torque around 4,200 rpm, but the torque is noticeably stronger from idle to peak and nice and flat afterwards. Its like driving a (strong) big block. On the street torque is king as you don't need to rev the engine to the moon to make big power.

If you are considering a complete build definitely put your money into a stroker it and if you want more later it's easy to add or change external stuff. Stroker kits are getting really reasonable now, 4.00" cast cranks are only $299.00, but I'd step up to a good forged crank if affordable. As for brands, I like Scat or Callies, but even an Eagle is ok.
