Whats your take on modding for that extra power

What do you guys think it would take to push this beast to 700 hp or just under? I believe it can get very close to that limit with long tube headers, full 3" exhaust cat back, intake, Retune and pulley possible.

Let's just take an SS... with all my listed mods, I gained around 55 rwhp

Baseline was like 355... now I'm at 410... that's a 15% increase... It "should" be the same here... maybe a hair more so with all that it's mire likely you'll be about 580-600 at the wheels with the pulley... Just cancel out the 15% drive train loss. If you want to talk CRANK hp, youd likely be 670-700 range... so yes if you're talk crank, you'd be right there. You could play with tune a lot and different pulleys. Also a cam and you'd be pushing 800 crank hp easy...

I would do it if I had the bank roll... at the warranty anyhow!

Check out Lingenfelter, Katech or Hennessey. They all have packages over 700 crank hp. The motor is still the lsa, so they are basing their packages on the CTS-V, but I believe it will be similar, if not greater, hp gains.

OOHH!!! I was wondering how much the forged Shortblock was. I will most likely be going through ADM (since they are 15 minutes down the road), and adding one more item to a very similar setup (obviously if I do it all at once, I won't be getting the supercharger upgrades), a 2.9L Whipple!!

Have you talked warranty with ADM? Just curious what he is offering on something like this.

There is one more thing i am on the fence about but i may go ahead with for the loss of weight and proven performance now I am not saying GM doesn't have it figured out but Lingenfelter runs this in there black drag car and I think it runs 9's but I am still undecided

Wonder how much weight savings there is compared to the big, cast iron pumpkin we have seen on the ZL1?

I've seen pulley kits on CTS-V with H/C push up to an alleged 19 psi on the stock 1900. This car also had an I/C upgrade, along with a lid spacer with all bolt-ons. If I remember correctly, this car was close to 650 at the tires. If you want 700 FWHP, with a 15% drivetrain loss (which I think will be closer to 18% for ZL1 because of the beefy driveline), you're going to be looking at a little more than 600 to the tires. If ZL1's rating doesn't change from 580, it should be around 500 to the tires, stock, so getting another 100 RWHP shouldn't be too bad. A consideration should be where you're coming from.

For me, I have to be as stealthy as possible because of emissions. For me, that means CARB-shorties (maybe...), no CAI (may not be completely necessary anyways, though I'm waiting to see if there's something like a Blackwing tube or something like that), and leaving a lot of the OEM exhaust (I'm planning on leaving pretty much all of the exhaust stock except the mufflers which I'll mod' like the 'Vette guys have been doing with their dual-mode mufflers). That means, I really only have pulleys, tuning, and maybe shorties. Given, a super-sharp eye will see the pulleys, but I think I might make it by with some creativity.

I believe LTs, bigger lower pulley, CAI, tune, and maybe a cam should net you close to 600 RWHP pretty easily. More boost is more heat, so maybe look into either an I/C upgrade, Superchiller, meth', or a combination of those for the 1900. Depending on what I find, I might consider a 2300, too... If you don't have to worry about emissions, it will be a lot easier.
