New heads/intake/rear end

I would start with the rear. Danas cant be killed but its gonna cost you more then the 8.8 will.[/quote[

How reliable is the 8.8?

Heads would be second. I dont know much about the Indys. I would talk to Ryan Johnson and see what he recommends. He knows his small block heads.

Intake would depend on the gearing of the new rear and what heads you get. If you get the indy heads they have a matching intake.

Well, I'm looking for suggestions here... what gearing? Put together a decent package in your head and then let it flow out your fingers into a post here.

Suggest:

Gearing
Heads
Intake

Keep in mind that this motor won't run on the street, only the track.
