So far, for our Z28's LS3R we have:

Factory Cold Air Induction

Factory shorty headers or, LS9 exhaust manifolds or whatever they use on the ZL1

ZL1 Dual mode exhaust, may or may not include the exhaust manifolds

LS9 type head internals or LS9 head swap
Need a high flow factory intake, something for 7000+ rpms

TR6060 M10 transmission (a transmission with only one overdrive would be best). Might be time to call Getrag here in Germany, the Germans engineer the lightest, most compact transmissions in the world then have them outsourced to China to have then built for 1/3 the cost. Nothing wrong with a 108lbs manual transmission that cost $2000 new...

Dry sump LS3 please

450hp/430lb ft and probably about 30-40lbs lighter than the 2SS's equipment.

Z28 suspension:

ZL1 suspension geometry w/ stiffer springs, shocks (non-adjustable), and stabilizer bars (FE4+Z51, no MRC)

ZL1 Brakes and two piece rotors (front and rear). If we can keep the curb weight around the 2SS, we won't need large diameter rotors which will be way lighter even more considering that the front and rears will be two piece.

19" forged or flow formed aluminum wheels between 22-26lbs a piece.

ZL1 tires would be hard to fit on 19s but the CTS-V has proven that 295s work in the back and with a 3800lb curb weight, they could really get down to business.

We could lose a lot of weight with two piece 14fr/14rr inch rotors all around and even more with 19" aluminum wheels with 255s front 295 rear. 40-50lbs in wheels and tires, 12-20lbs in rotors. The suspension upgrades will likely be heavy but the rotors/wheels and tires might bring weight back to the green.

Edit: There were rumors of an LS8 that was also suppose to be supercharged, what if GM didn't put a supercharger on an LS9 and just let it flow naturally and called it an LS8. Can you imagine a 6.2 liter V8 that weighed 388lbs? It would be coveted by every road racer, autocrosser, drifter and hot rodder in the world... and would be expensive.. but I'm willing to be less expensive than an LS9... Lets do that, a N/A LS9 (called the LS8) using the carbon fiber LS5.5R high rise intake for high rpm power and call it a Z28. Or, we could take the 3.26 stroke of the Vortec 4800 V8 and make a 338ci/5.53 liter if the crank will fit... say hello to the RPM's and say bye bye to our torque, horsepower and RPM's are more important than torque for the track anyway and now we won't have to worry about exceeding our transmissions torque rating.
