No. LS1 WS6s were done by ASC.
No, not "a lot" at all. Probably about a ~10hp difference between the two model years.
'01+ LS1s have a less agressive, lower lift cam. But they have a better intake, better exhaust manifolds, and heads that received a slightly better casting process....those are the reasons why they feel/run a bit stronger. The net result is that the '01-'02 cars usually make about ~10hp more. The performance difference is by no means major.

This thread is irrelevant.
It is just a appearance/minor performance option, thats it.
Nothing more, nothing less.
I wouldn't say the 01-02 'had more *****' than a '98, it's all about the driver mod.
Also a 13.7 is not a 1/4 mile to use as a benchmark, they are much capable with better times with a better driver and better tires.

Anyway, again, all things being equal (meaning cars that are 100% stock with no SLP options like Blackwings or dual/dual), you won't see more than a 10hp difference on average between an early LS1 car and a late LS1 car.
Some people like to think that their late model cars have some sort of 50hp magic over the early cars. As an owner of both, I'm here to tell you this is simply not the case.
Having said that, if you put an '02 SS that was optioned stock with a Blackwing lid and dual/dual exhaust against a '98 Z28 that's stock, then you will obviously see even better times out of the '02 car. The Blackwing and dual/dual are just as good as any other air lids and catbacks, so you're giving the '02 car an additional ~20hp advantage over the early car, plus the ~10hp advantage that it already had. '98s and '01-'02 had the same size injectors. '99-'00 had smaller injectors. Injector size was increased in 2001, not decreased, bringing it back to the size used in 1998.

Just a quick note on what I remember and why that video calls the SS a Z28 SS: In `96 and `97 SLP did the first SS. They took a stock Z28 someone ordered and added the ram air ducting, 2OTL exhaust along with suspension upgrades. Dealers ordered the car from SLP. The car was "built" by SLP. To Chevy the car was always a Z28 as there was no official SS at the time. Most mags at the time refered to the SS as SLP's Z28 SS.
Starting in `98 Chevy offered the SS package and it could be ordered direct from GM; GM installed the base SS wheels (at least starting in `00), sway bars, intake plumbing and exhaust and SLP installed the hood, spoiler, bump stop spacers and any extra ordered 2nd sticker options (Y2Y). At the point Y2Y options were added the car again became "built" by SLP like the 96 and 97, hence the extra stickers that had to be placed. At first the mags still called the SS the Z28 SS as they did in `96-97 but later dropped that name for simply SS. The car in that video is a early (98-99) SS, can tell by the mirrors, so would have likely been called a Z28 SS.
Wording on the title/insurance/etc depends; offically it is a Camaro Z28 SS. Firebirds are the same way plus an extra trim level: Firebird Formula Trans Am WS6, all V8 Firebirds are Formulas just as all V8 Camaros are Z28s (or B4C).

My 01 Z28 went 13.1 @ 108mph on a 2.1 60ft bone stock... Considering the conditions were about as good as it gets (-130ish DA I believe) I would have to agree with them being no better than previous years considering the number of 98~00 cars who have done even better than I did.
It did put up 324rwhp/341rwhp torque with just free ram air done to it.

mm&ff took a 99 z28 to 12s stock... They also got an ss to 12s stock in 2001.
