Dialing in stock bellhousing??
Anyone hear of this or have this done? I've heard of this with a scattershield.
Did GM perform this at the factory??

I have never done it, never really thought I needed to, probabaly pretty straightforward with the motor out and a dial indicator.

I have done it with my blowshield. There is no way GM spent the time to dial in the bellhousing. Not a bad idea to make sure it is in correct alignment with the crank. It only takes a little time and will prevent problems later on.

If your total indicator reading is .007 that means you are out .0035. Lakewood wants them within .005 so indicator reading of .010 is OK. Mine was in .008 total so I had .004. Really splitting hairs here. If you are out .007 you should be OK.

I always dial them in, always. It is easy to do with the motor in the car and no clutch so I take the few extra minutes to confirm that it is within specs.
Will it really matter??? I don't know but if things are turning that many cyles over the coarse of years without being perfectly aligned it has got to take it's toll.
We blue print motors to get the most out of them why not make sure the crank and the transmission main shaft are on the same plane???
It is really easy to correct any runout with offset dowels and all you need to check is a magnetic base and dial indicator.

How easy is it to do on jackstands ? What is the proceedure to follow ?
If the motor is in the car I assume you have to take the tranny out ? I hate getting under that car on jackstands gives me the creeps

You have to take the clutch and pressure plate off. The magnetic base attaches to the end of the crank. Seems like t'd be a PIA with the engine in the car. I think I'm going to do a GM and just bolt her in.

Yes you have to take the pressure plate and clutch off. It is a project but I had the trans out to swap in the Tremec anyway. I did it all on jackstands on my back. With the trans out and the car in the air I am able to sit somewhat uprite in the trans tunnel where the trans is. I'm fairly small though. 5'7" and 150. Some of the bigger guys it would be tight.

Not for me that gives me the ****** 
I might have to do it somehow when I get a scattershield
