Neutral balance to a 360 crank?

finding the early ones (the full floating ones from the factory) these days might be slightly easier than a set of 198s for my slant build... but still not exactly "easy"...this many years after they went outta production. what rods would a 72 360 have? (Im thinking all 360s had the "heavier" ones) I know where there's a wagon with a 360 short block in it, looks like never apart since leaving factory... only 360 I have seen without those damn dished compression (and power) robbing dished pistons that every other 360 I've ever seen apart has had.

360s have the 645 rods.
