300bhp/ton

Depends what you want. Also 500bhp SAE Net is probably over optomistic I'd guess nearer 450-470bhp SAE Net as a more "real world" number.

I didn't see any intake listed? Ported FAST 90 with a NW 90mm TB would be good. If you plan to stick n/a then LT's over the mids and a better catback (3.5" tubing) or duals.

More radical cam setup.

Different heads (probably not worth the cost though).

Gears (4.10) and/or 12 bolt.

LOADS of suspension and chassis mods including brakes.

Nitrous would be a strong candidate.

Or maybe FI (turbo or supercharger) although you'd probably need to drop the CR to make the most of it.

Cosmetic mods

Or if you really feel you're done, flog it and buy something else.

I'm not sure what intake its got but I've been told its an LS6. I'm definitly going to do 4.10s and some long tubes. I'm most likely sticking with the 7.5 because even with the power its got, its not hurting on the street. If I try to launch hard it just spins anyhow. If I were going to supercharge it what could these internals handle you think? Being that they're the stock rods just with arp bolts.
