To stroke or not to stroke......
Hey if everyone built motors the same way they would all be stock. What fun would that be ?
Anyway you look at it the extra stroke is going to add torque and/or lower the rpm range of the motor making it more fun on the street.
In my case the 4" crank would be the perfect way to make my motor more streetable. With a 7000rpm peak, 1200rpm idle and only 406ftlbs of torque at 5300rpms its not currantly the tamest thing.
