A 400 abc with 3.75" stroke and 5.565 is much more likely to bend /break a rod from combustion pressure than any stock stroke/6.09/6.10 Ls rotating assembly. Rpm kills rods, flexs cranks which wipes out bearings. The cap will stretch putting a side load on the bolt causing it to break. Arp bolts take that side load better. RPM IS THE#1 ROD/BOLT KILLER heavy piston make the stress much much worse. It's simple physics, the heavier the rod and piston the harder they jerk on the cap/bolts/crank multiply that times more speed and bad things can happen.

I would say high RPM combined with less-than-great tunes have killed way more motors than straight up power. Obviously, every motor has its breaking point but if you keep the power at a loosly reasonable level, keep the RPM down, and get a spot on tune you will be surprised at how long the stock parts will last.
My stock bearings and a couple of rod bolts personally gave way to a missed 6-4 shift that ended with a 10,000+ RPM rev followed by a a spun rod bearing that ate almost 1/10" of iron off of my crank.
