The 393 is a stroker combination, that uses a slightly longer 3.850" stroke for more displacement and low-end torque. Compression ratios ranging from low to high make this a versatile setup, available in a variety of performance levels.
This is the most robust stroker combination available, using a 4.000" stroke to arrive at 408 cubic inches. Due to the long stroke this combo makes monster torque, although at the expense of top-end RPM. Regardless it is still a great setup for street/strip applications where the RPM aren't extremely high to begin with. Applications range from low to medium compression making this a fantastic choice when paired with a supercharger!
This is the largest cubic inch displacement we offer for a stock style Windsor block. It uses a lengthy 4.170" stroke to yield 427 cubic inches. As expected, because of this stroke, this motor will be very bottom-end heavy and is best suited for applications such as street cars, tow rigs, and trucks where RPMs will be somewhat limited. Compression ratios range from low to high.
This configuration is identical to a 418 (4.100" stroke), This build uses a DART block for added strength making it great for high horsepower applications.
