lastly, im using a new 3L crank so my front pully matches correctly, and so my flywheel matches correctly.
and i know about the difference in displacement, thats why im asking about any differences in the RODS, i know the pistons are larger.
i want to be sure the VG30 crank works correctly with the VG33 block, rods, etc.
finally, (sorry for the bit of rant) - thanks for the link.
