Destroking means decreasing the stroke thereby decreasing the overall effective
cubic
inches of the engine.
The only advantage this can give is a higher redline if it is balanced
properly...which
is only useful if the whole engine/hp/torque package is designed around that
whole
theme...in the case of an old truck, one has to beg the question...why? I love
high
revving oversquare engines but this isn't an early Z-28 road racer trying to
stay under
a displacement limit.
Since you have a 400, don't mess with it.
