440cid is the max recommended. This is NOT a stroked Windsor though, it has a 4.185 bore potential and when combined with a max recommended 4" crank your at 440". A Windsor, with a 4.030 bore needs a 4.170" crank to get 427", not an ideal combination for a high performance motor. Typically, when cubic inches are equal, the large bore\ short stroke combination will have a higher rpm torque peak but a flatter curve. The small bore\ long stroke combination will peak at a lower rpm but will have a peakier curve. Flatter torque curves are easier to drive.

This block finally allows Ford guys to copy the combinations that have been available to the Chevy guys and for a reasonable amount of money. With the aftermarket standardization of pistons, rods, cranks, and now blocks, only the cylinder heads account for any performance differences between the manufacturers.
