There's more to it than just the crank though. You'll get 402" with just the
crank (and you'll need to notch the block) and 408" with the pistons @ .030"
overbore (also have to notch the block). Also, there's much more involved than
just crank and pistons as well. The stock rods (while they are adequate) are
not recommended for the 408 Stroker as they have to be reconditioned and the
cost for this (with the pins) is the same as a new set of I-Beams (all ready
for installation).
If you replace the crank, you might as well rebalance the reciprocating
assembly for reliability. This presents another option: Internal or External
balancing. While Internal balancing may be what most like to have done, it is
more expensive and will require a different dampner and flexplate. Have it
externally balanced with a new Mopar flexplate and dampner or...save a little
bit of money by having your existing dampner and flexplate used for the
balancing.
