I think it is possible, but not feasable. your looking at .120"
overbore from stock (3.92" to 4.04"). I would not guarantee that there
is enough material to permit this much boring. Having the bores sonic
tested to see how thick they are is worth while but expensive. Also,
with thin cylinder walls, your looking at possible cracking and
overheating.
I would find a 340 block first or get a mopar block from mopar
performance.

They do, but the older book has more information that was left out of
the newer book. Besides, I was not impressed with the new engines
book. Not enough information on the magnum engine. I got more out of
my FSM for my dakota than the engines book.
