Most dependable extreme setup?

HOWEVER - N/A is the most dependable no matter what the goals are. Sorry. For FI, turbo's (either twin or single) will be faster all else being equal but they will also be more expensive and require more involved tuning in most cases. Supercharges are a bit simpler, but can have belt issues.

If you can get a 572 or something though, then I would probably agree. But I dont think I have personally seen anything over 502 in a modern Vette.
With a FI setup you can run lower revs, milder cams, etc. You might get more heat from inefficiencies in the turbo or super, but intercooling has advanced to an amazing degree. A well thought outsystem would be able to deal with this heat effectively while sparing the bearings, rotational assembly, input shaft, block, valve train, etc high rev abuse. Which IMHO is the #1 killer of all engines.
For say 900WHP, I would say the most reliable route would be a 408 with a single and perhaps a shot.
How extreme do you want to go? Build a 454 ci LSX motor with a 3.3L twin screw being fed by a 101mm thumper turbo ( with a 200 shot of nitrous to spool, of course). Sorry, but the "extreme" question lends itself to idiotic replies.

If you go turbo, you'll definitely succeed in the whole "not being good" part of autocross. It may be best for a straightline track car, but that's about it.
If all you're looking for is high 10s/low 11s, just do heads and cam and bottle it. It'll be a lot more dependable (and cheaper) than a turbo or blower setup.

I dunno about not being good at autocross. I won SM2 my first time out (having never autocrossed before) and beat out the top points guy by a almost a second. I blame the incon kit for getting me to the turns faster. 
I'd go with turbo(s). you'll spend more money to get it going but it will be very street friendly with oh **** performance when you need it. having more linear power brings a supercharger in close second but belt tension and crank pinning scare me off.

900whp is not so hard on a stoked 350 with Turbo,Do your homework and you will get there
With FI the pressure and heat of high boost kills rings,r.lands ect and blowby will occur,heads and mains will allso see alot of stress
Considering this was brought back from the dead.
My D-1 setup is still kicking with some minor adjustments. Had some belt issues when I first brought it out in April this summer, but now everything is okay again.
I expect another good summer of daily driver 700 RWHP fun Putting ~100 miles a day on it.

Personally I have gone the supercharger route but not the Turbo route.
I would still vote blower with a good bracket/pulley setup like the SDCE for your goals.
ATI D1SC...Even the bigger 4.5 inch dual intercoolers would work fine for you at the power level you are looking at and be dead reliable with the right fuel/tuning especially if you go forged...

I've been to chicago twice (1000 miles each way), augusta and orlando a bunch of times, new orleans, etc. almost went to LA but the job fell though... 30,000 of road since my last post. still have oil pressure and power to pass in a second or two... lol
