Nothing, Read the FAQ in the top of the threads (Stickies at the top of the pages) if all else fails you can use JRP's sig, or the search)
But to save you the trouble...
SS has a different hood, spoiler, higher flowing muffler, larger front sway bar, and i believe different LCA's. 17" wheels as well. The Air box also has a gap in it to use the "RAM AIR" larger than stock. That is really it, all LS1's are overall the same and prodcue similar power. The years vary by not much...maybe a cam difference, heads, intake manifold....but other than that its the same between the same year. So a 98 Z and a 98 SS have the differences i had posted above ^ a 98 and 99 will vary however

The extra 25 HP cam from the marketing department! They had to justify a $5K+ pricetag for a different hood, spoiler, 17" wheels and slightly upgraded exhaust. In actuality a $100 aftermarket airlid on a z28 would undoubtedly out perform the $5,000 SS package. GM of course dosnt want anyone to know that. Least of all the vette owners who paid double the cost of the z28 for the same HP.
The LS1 motor is essentially the same no matter what car it goes into, z28, SS, ws6, vette or GTO. They all put out ~ 340 - 350 BHP.

Exactly. The 25 hp is just a # thrown out there by the marketing department for good measure. Neither the #'s for the Z28 or SS are close to reality. SS's and Z28's all dyno within the same range. A good aftermarket lid and catback will perform better than the stock SS stuff anyway.

the SS package is just a sticker from SLP 17' wheels hood and spoiler. not even better exhaust, everything else was extra options, you could get a lid, chrome wheels (10 spoke or ZR1) a front grille, floor mats, exhaust even headers from SLP.

We're talking about a fraction of a percent HP increase. Tolerance and build variances from motor to motor will impact the power output way more than having an ss hood or not.
Stock vs. stock, the winner is the guy who took the bigger dump that morning.

Besides the base alterations you could get the auburn differential, chrome wheels, performance exaust, performance suspension system and then all the other goodies like floor mats and such. There are differences in a fully optioned SS and Z28 wether they like it or not. It is the exact same motor.
The SLP d/d exaust isnt that bad, check numbers in my sig, it flows just as good as any other catback. The Bilstein HD's, SLP pro-rate springs, LCA's and PHB give it better handling than the z28. I repeat it is the exact same motor but to say there is no difference between the two cars is absolutely incorrect.

I feel that for the 4 or 5 grand difference, aftermarket stuff would give you more bang for the buck. Ill eventually get an SS hood and spoiler after im done making up for those 25 missing horses! In the looks department, I will gladly admit to the SS's prowess over my Z. For what its worth.
