Actually, you can bore it out and use at max .040 oversized 3000 pistons
without any problems.  It sounds like some one would be able to find a
use for it.  As for racing I would suggest going all aluminum, DMD makes
a sweet 3.8 litre.

If you bore out a 100-6 block to 3000 specs, you must bore each cylinder
.155". You'll have better cooling allright because you'll have water in
the
cylinders. Well, maybe not in every hole, but the cylinder walls be be
so thin
that you are sure to encounter leaks. This maybe OK for someone that is
willing to take this chance with a 100-6 street driver, who just
happened to
have a set of good used 3000 pistons lying around, but no racer in his
right
mind would do such a thing. A racer would start with a 3000 block and
bore it
out as much as the rules allow.
