411 swap did not go well

I went back thru your thread. I dont see any mention of oil pressure. How is it? If it was something as critical as bearings and making that noise, I would think you might see it in low pressure. You also mentioned some kind of a possible timing issue. Log the vortec cmp pid and see what it is. Maybe something happened to the distributor.

The top drivers side transmission bolt, I ended up taking a hole saw to the floor boards to get out.

I beleive the dust guard you are refering to is the driveshaft carrier bearing.

Thats what it was. I was laying awake last night and finally it popped into my head.
Dad listened to the video's with me, and he's thinking flex plate. (another person's opinion for what its worth)
I'm hoping thats what it is. $45 part sounds better than a whole new motor. but then again, you could always go bigger.

nevinsb: I think they should have holes like that from the factory. Or just more room.

Good Luck,

I think the carrier bearing is only on the extended cab 2WD models. I was trying to figure out what you all were talking about since I've only owned short cabs. I'm not sure how the drive shaft would make that noise while the transmission is in park. I'm still curious why it would run fine until doing the PCM swap though. Hopefully once you start pulling things apart, you can isolate where the noise is coming from.

My drive shafts just had the rubber dampeners on it. The top one is a short cab long box, the bottom is a short cab short bed. *Cough* note the V2 sitting on the counter

The oil press is low @ idle (~19psi), but jumps up to 40ish on throttle (~1000rpm).
I'm not familure w/ the CMP. That's to say, I'm not sure I've seen one. I'll guess it is on the timing cover. PIDs show a CMPHI & CMPLO. I'm not sure why you need a CMK when you have a CKP.

I have that exact model. It's the neighbors. This is the only way I could tell it was coming from the #6 cyl area. The noise echo's all over the engine bay. It still doen't caompare to the bellhousing noise. (Loud)

Sorry I meant the Camshaft position Retard (vortec) PID.

Rest your hand on the distributor while its running.

Yes, it is an ext cab. I wanted to replace the whole assy w/ a single drive shaft a few years back, but I'd need to remove the frame brace. I decided against it.
