I'm going to say it may have been overrevved at some point, stretching and stressing the rods a bit, which has been known to happen in our engines. The weakened rods would then not take nearly as much torque before yielding.

I missed that part in the shitting OP. Is this a 2554? My own made the numbers in my sig. And it says 12psi, but I think it was 11 at peak torque.
So I'm 10ft/lbs down and 15hp higher, with a 1.6.

Well yeah sorry what I mean when i say it ran perfect is that it seemed perfect. I.e no misfiring or anything. Obviously I have no idea if det was happening all along.
The rev limit is set to 7.5k and it saw that a lot in n/a form and even a few times in the 4 days it ran with the turbo.
Here's pics of the head:
Quite sooted up.

I had my rev limiter set to 7100 and it didn't need to go that high because the meat of the powerband was below there with a log manifold and stock heads. And I hated to push it too hard because I wanted it to last.

Does your "mapper" send his emails by carrier pidgeons? Or telegraph?
I mean seriously, this takes all of 2 seconds. Phone call, "can I have my map and logs", email, voila....
Or, since you said he is "well known on here" I'm guessing you meant MT? In which case he can just post it up and the included logs from his tuning session.
