Quick mods

What would be great mods to jump the hp up in my aurora? Looking for mainly bolt ons. Is there a huge performance index for an aurora?

The answer is: there really are none. You can look into www.northstarperformance.com for a PCM tune. Outside of that there really isn't anything aside from say nitrous which I would be worried about doing on this motor and maybe a turbo which would require extensive modification. I don't think anyone makes any performance upgrades for the northstar let alone the 4.0 variant unfortunately.

You can look to the standard cold air intake, performance plugs/wires but usually the gain is minimal/negligible.

There's little to no aftermarket performance parts because these were grandpa cars! RCA nailed it:
exhaust
intake
wires, coils, plugs
pcm tune
vin 9 cams
weight reduction
that's all
