I don't have any logs of the incident. I haven't had any need to log for a while now. The tune was rock solid. So good in fact that when we disconnected the pcm to drop the transmission to install the new convertor (a Yank 3000, btw). It needed virtually ZERO learn time. It started and idled fine. The rest of the tune was equally good. No problems there for sure.
I would say that the rpms were closer to 3000 when it let go. Not very high at all.
I was coasting down on the freeway because i was concerned about the possibilty of law enforcement officers hiding on some upcoming overpasses. Earlier in the evening we hammered on it a bit, but I wasn't doing anything out of the ordinary when it let go. Everything was warmed up and good to go.
New plans include a 402 or 408 and FI, of course
Definitely heads (only because mine are trashed)... maybe headers.

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!

From: LT1 land...the "409" of the 90s!
well we are 99% sure the failure was a rod bolt.
That leaves out the tune and just about every thing except non-compresion loads on the Rod
We will know more after the Engine comes out that is for sure. What we do have show no signs of Detonation are a bad tune
Parts will start hitting us next week
Truck may be running in two depending on some parts showing up

I think I will get some good results after I swap cams, I have other problems that are not head related. My main problem is in the valvetrain, when this gets straightened out it should be close to 400 at the wheels
