Anybody ever swapped out a heavy( stock) rotating assy for lighter aftermarket?

Just curious if anybody has ever swapped out heavy factory pistons and rods for lighter aftermarket units, and went back to the track?
Reason i ask, is i have a completely stock 360 bottom end in the motor i currently am using.
I also have a 418 shortblock laying around.
Having been there, done that before, instead of at this upcoming seasons end using the 418, thinking about just upgrading the 360. I suspect the 418( it would be 12.8 ish to 1 abd maje some low 10’s steam, would be enough to break my 8.75 rear.
Think the 360 wouldnt. Be slower and good bit less squeeeze and torque.
Gotta believe a light assembly would accelerate and shift recover and notable amount quicker

lol.. edit.. Getting in the racing mood because i recently had full hip replacement and didn't know how soon i could literally get in and out of my Dart( it sits low). Well, yesterday i gave it a shot.... passed the test. So racing season is a reality
