They're all forged cranks. I think the 2013 Boss crank and damper were weighted a little differently than the GT crank.

went over the posts on springs and am still undecided about the stock Boss springs or an upgrade... I would have thought that LM intake cams would be fine with the Boss springs?
I was thinking the same. A clip which was not properly seated could have been making its own groove before the failure. Are there any signs of the clip wearing on the cylinder wall?
How high are you reving your engine and for how long? I think you're fine on the intake cams since they are still 12mm lift. I think the concern is on the exhaust paired with a heavier valve and high sustained rpm.
The other thing I keep harping on...are the oil squirters. Why else did Ford include them for ALL Coyote variants AFTER the Boss? (Excluding crate engines)
Common misconception. They're only missing for part of MY13 production. Definitely back in for ALL Gen2+ starting with MY15 cars.I thought they were deleted in Coyotes sometime in 2012 and have not been reintroduced since.
A 4-3 downshift at ~6,800 rpm jumps to 8,700...
