Been looking into that, and I wish I could run a solid plate like for the 360.
Problem is, no one seems to make one.
So far the only upgraded plate I have seen is for the 5.9 diesel.
I started hearing odd sounds bouncing back off the rock walls and guardrails miles before it actually broke, so I was going easy on it.
I was in third gear at about 2k rpms when it let go and started shaking.
I pulled over, put it neutral and it still shook.
Then I shut the engine off and looked under the car, (no fluids leaking)
Then I started it back up babied it the last few miles home.
At the time I thought "Whoa, I just fired it back up" and everything about the starter and motor turning over sounded completely normal besides the out of balance part, and how could that be if the flex plate is that busted up?
I really do suspect I'll find the converter hub to crank snapped off and the center of the plate trashed.
We'll see.
