Not to butt in on Mike's deal here, but he may be in bed. <G>

SFI once stood for SEMA Foundation, Inc. (SEMA is now not involved but SFI
kept the name) and does the standards for racing equipment - bellhousings
being one of those pieces.  A scatter shield is basically a term for a
bellhousing that's not suppose to explode but rather contain a
clutch/flywheel explosion.  A scatter shield must meet SFI Specs to be
accepted by and X-HRA body.

What Mike meant was that due to manufacturing tolerances, the critical
alignment of bolting the unit to a block may not be exactly aligned due to
the dowel pins in the block not being exact.  Most mfgs have offset dowel
pins available that you can use to align the bellhousing perpendicular to
the block insuring the transmission input shaft is dead-on straight with the
crankshaft.

Thanks Mike,

Is a scatter shield the same as a SFI bellhousing or is it an additional
piece of metal that is welded on top of the bellhousing?  

Also, What do you mean by "Dialing it in"?  I would hope the garage doing
the install already knows this, but I am curious and would like to have some
background before I ask them.

Thanks,
Steve

Absolutely yes, buy a scattershield.  Your feet are far more expensive 
than a scattershield.  I've seen pics of cars pretty much torn in 1/2 
from an exploding flywheel and/or clutch.  Not good, and definately not 
worth the risk.

Either a Lakewood or a McLeod.  In either case, you need to dial it in 
to ensure proper alignment.  The McLeod's tend be a bit better on 
alignment right out of the box.
And either will work with a GM TREMEC TKO-600.   It's designed to be a 
direct bolt in replacement for a Muncie (utilizing a 26 spline clutch 
disc).  Here's some swap details if you want/need more info:
