I've indexed a few - mostly on stick shift applications, where I feel it is necessary if serious competition-like upshifts are planned. I zeroed it in with eccentric dowel pins that I turned. Nowdays you can buy eccentric dowel pins.
A powerglide is more forgiving with a flex plate and converter but I have checked a case or two before buildup, to make sure it wasn't waay out.

Most blocks will need tweaking if you really check them closely. I think anything up to about .005" out is acceptable, like FTF said, stick trannys are more succeptable if their out too much than autos are.

If you have access to the stuff to do it with, then by all means give it a shot. But I wouldn't be to concerned for just a street engine.

I might not go all the way to zero with it, but it's worth a look if you haven't had that belhousing on that block.
My, what a steep learning curve. Erik II#5155

If you have had the engine line bored I would definately do it. When the engine is out of the vehicle and you have the bellhousing and a mag base dial indicator why not spend the few minutes to make sure it is with tolerance. It surely will not make the front trans bearing unhappy.....
