If the stroke is shorter, then theoretically the rpm range for the engine
would be higher. I have a brother that races dirt track and runs a 400
block with a 3.25" stroke crank so that he can use numerically higher gears
and rev higher coming off corners.
In a street truck I'd think the cubes would be better than rpm especially if
you plan to use the truck like a truck and include hauling or towing. If
you are going to drag race, then maybe the destroke would be useful.
