I know this is pretty vague, but I am trying to piece together a combo to go in my Dart.

Rough plan:
~3000lb A Body
G3 Hemi
Holley EFI
T6 frame turbo (S480?) or smaller twins
turbo cam
E85
Powerglide
9" w/ low 3.xx gears (once the 8 3/4 lets go)
275/60 tire

Ultimately, I'd like to be solidly in the 9's.

Doing some reading, it appears that a stock 5.7 or a prepared factory shortblock will not support much. 6.1 would handle more, but they aren't exactly common.

It would make the most sense to get a complete take-out, so I have all of the supporting pieces. I could then upgrade the 5.7 shortblock, and it should support a fair amount of power from what I gather. If I am upgrading the rotating assembly anyway, is an early 5.7 or Eagle preferred? Rod and pistons are a no brainer. good gaskets and head studs, call up someone for a cam. What other upgrades would I need, and how much power would it support?

I now see the hellcat shortblock is available, but I don't know how much would fit if I had a 5.7 donor.

I have nothing so far, aside from the tired LA the hemi will be replacing, but I'd like to try to be smart about it. Knowing what I am after, I won't even bother with a stock engine and risk driving over the crank.

Any input or links to other builds would be appreciated.
