Damn it that sucks! I'm sorry to hear about this. Looking forward to hearing about what happened. Hopefully the explanation is simple, but usually if a bearing spins during break in where the revs are not too high, boost is on wastegate pressure and oil is a little thicker, it could mean lack of oil pressure, incorrect bearing clearances, a bearing moved during final assembly etc. Either that or the bearing halves are not seeing enough crush, which would indicate the wrong size bearings or excessive wear to the rod/main bores.

I was using brad penn break-in oil. Oil pressure was around 120 on cold start and 20-30 around warm idle. Kept a keen eye on OP and AFR. No boost but could hear it starting to spool close to 4k rpm. Looks like all the rod bearings were ****, main bearings also were done. Crank is toasted. Pistons have ****ty side wear. Rust was found in the bearings and I can assume this is what caused the issues. Waiting on the shop to let me know if the cylinder walls are good. I'm currently at 85.5mm bore and I'm hoping it doesn't need to bore to 86mm but If i need to it will get done. Don't think I had shavings as it was caught as soon as it happened.
Currently, needs new crank, rods, pistons, machine work, oil cooler, and oil pump. I'm might just go the 2.3L route.

Such a bummer dude, sorry to see this! Who is going to build the new motor? Not for nothing but Sean (LGTD) called this fate back when you ordered your short block. Have they mentioned anything in regards to assisting with the rebuild? I dont understand why there would be rust present on the bearings. Also, if both rod and mains were toast that screams shoddy work as its not like you just lost one unless you first lost one which took out everything else. Either way hope you get it back up and running soon!

Yea man, I'm unable to get in contact with the person I bought it from so I'm going to press that anymore. Nor the shop or I know how rust was in there...
Update...My rods, pistons, and crank are toasted. My block just came back from the machine shop and GOOD NEWS, I don't need a new block or bore to .040..They holed, lined, ect and I'm at .020 over. New TT I beam, Wiseco HD pistons, crank, oil cooler, oil pump, and gasket kit were ordered. I would've pulled the motor and built it myself but I'm at the point where I just wanna drive this damn car. The shop is doing all the work and I should have it back in a couple of weeks. Down side is that I would make the May track day and I'm moving to a new job that 20mins from the shop..lol
