oh dude, that sucks. i've gotten lots of 408 price quotes over the past few weeks, confused as hell. Now I'm trying to decide to go NA, keep the tiny whipple, go turbo, or get into a procharger. ahhhhhh, PM me if you want some info on the quotes i've gotten.

I think Cory had let off for a few seconds, 2 or 3, maybe 4000 Rpm or so when it let loose in 3rd. Unfortunately, stock rod bolts letting loose are more common on decel with FI...The sad part is we were just talking about the problem some have with stock rod bolts again, that night....Looks so far, that the rod let go and got caught by the crank, pushing the rod against the block snapping the rod in half and pushed the oil pick up tube out the side of the pan and the rod out the bottom. Anyway, we'll know more after pulling the engine and looking... Looks like some of this

Glad to see you're taking it well. Breaking something major always sucks but it's ones ability to literally pick up the pieces and keep on running that defines you.
Can't wait to see your new project

Awe man that sucks!!! Makes my broken piston look
Wonder if the laughing gas had anything to do with weakening parts? I put in Katech rod bolts when I swapped mine just for that reason. At least it didn't take out any steering/braking parts after it let go. Good luck with the new build!
