You'd be close with these mods, but if you want to be sure, go with a head/cam package.

I've read individual threads about air boxes, catbacks, headers etc. but I don't think I've read a specific thread about what it would take to accomplish something like the above mentioned hp increase, and approximately how much it might cost assuming I do no work myself - mechanically challenged.

The usual bolt ons will get you close if not there. Long tube headers, thermostat, high flow cats, cat back exhaust, airbox, tuning. Is your car a manual or automatic?

A couple of provisos, I don't want to voidmuch warranty if I can help it,

Then don't touch it. If it is an MN6 and you add 50HP, I personally wouldn't bother with the gears if I didn't want to get into too many warranty issues. But even with headers, should you ever need another clutch the headers may have to be removed to install it. And the dealer may balk at removing your headers to install it. Depending on the dealer the headers and PCM programming could affect your warranty.

If its an automatic, then unless you change the stock gears, be they 2.73s or 3.15, IMO there is no point in adding 50hp with either of those gear choices. With an automatic, I'd do gears first to at least 3.42s and possibly/ probably 3.73s.

Adding 50hp to a 2.73 geared car gives you what? And IMO 3.15s don't offer much above 2.73s and I have driven Vettes with both. Neither is a "performance" axle ratio.

Its my opinion that if its an automatic, unless it has at least 3.42 gears in it whats the point? But thats just me, and of course this will kill your warranty.

Man, I know I shouldn't start down this road, but.................

........You get used to 350 HP after a while. But this modifications to increase power stuff simply cannot be undertaken if you are at all concerned about your warranty. You will put parts of it, probably important parts of it, at risk.

Wouldn't it be about +50HP if you put on Z06 heads and cam? My guess would be that it would still look stock for the dealership too. Parts could be found in C5 parts for sale for a decent price too.
