I have basic understanding of what they did. But not sure why, is this a viable mix of parts? I'm thinking not really even though it may function?

So : 8 bolt hemi crank with bushing for 4spd. Hemi rods, hyperutectic pistons
dont know the deck height.

Hemi rods are .090 longer. And bigger pins, heavy rotating assembly, same stroke .030 over bore on a 440 block.

Why and Huh?


440 standard rod is 6.760”, street Hemi is 6.860”, 396 NASCAR Hemi is 6.960”, and there are 7.06, and others.
440 wrist pin is 1.09”, race Hemi is 1.03”.
