Sneaky Power
If one were to modify the Z, but want to keep any changes hidden to the eye what would you suggest?
My initial thoughts would be:
Ported Heads with upgraded internals
Ported upper intake and throttle body
Someway of changing the factory intake.
Just something I was sitting here watching BBC Top Gear and started thinking about.

Most non-Vette people wouldn't notice an LS3 under the hood. The LS3/L76 intake manifold looks amazingly like a regular LS1/6 intake when you remove the cover. I say build a large-cube LS3 with a mild cam that doesn't lope hard.

I did just that, kept the stock ti mufflers. 495 rwhp/465 rwtq. At a light, or just crusing around, seems like a stock 346 ls6 till I get on it.

Get your 243 heads ported, polished and milled but tell the shop not to remove the 243 casting number, either shorty headers or LT headers like American Racing or XS Power with cats, Stock TI mufflers, a sleeper cam like a EPS 218-222-116, TPIS 90mm LS6 intake and VMAX CNC LS2 TB, VARARAM or Killer beehive CAI, Underdrive pulley. It will look, drive and sound stock except for the CAI and headers but be stupid fast.

X-pipe --> Definitely not. I didn't say longtube headers, just an x-pipe that goes after the stock cats and before the Ti exhaust.
Cam --> Not if you choose wisely. A 220/224 on a 114 should sound pretty close to stock, for instance.

440rwhp/405rwtq. I've since added nitrous though, but its really no longer stealthy.
228/232 cam, ported LS6 heads, American Racing headers, and a few other things. I kept the stock Z06 exhaust though to keep it a little quieter.

As everyone else already mentioned about stock re-worked heads, 3.90's or 4.10 gears, small cam (nothing too lopey)...and instead of going with LT's or even shorties; if you want to go stealth, pick up some LS7 manifolds and mid-pipe. Also, as far as the intake goes, I've seen some guys cut the radiator shroud which will be hidden underneath the stock air box...same concept as a Callaway Honker, but using stock components.
