Paul,
	Don't know much about northstar/aurora, but I can answer some of your LT1
questions.

1) very little interchanges between the earlier SBC and LT1. The Block, heads,
and intake don't interchange.

2) The LT1 block has provisions for a normal distributor The only thing that is
missing is the whole and clamp in the intake manifold. If you use an old style
computer, I would try to adapt an HEI distributor. Gm sells a carburator style
intake manifold for use with the LT1 crate engine. It allows the use of an HEI
distributor.

3) If you do want to try to play with the LT1 PCM I have found all the tables in
the 94-95 PCM.
