There is a chart in the first chapter of my big block book that shows you where the torque peak will be given a combination of cubic inches and cylinder head size.

You can either design the engine around the chassis or change the chassis to work with the engine. If you add inches but keep the same heads then the torque peak will drop. If you had the perfect gearing before then you'll need to adjust your gears to work with the lower torque peak.

The nice thing about running a stroker motor is that even if the peak power stays the same, the RPM at the stripe goes down which should mean extra life for a lot of the engine parts.
