RE: LS1
Yes, JD and I and a few other LS1 guys have said that many times. In fact, he stickied an LS1 vs Mach 1 thread that discussed that, but "SS = Z28 = Firehawk = WS6" isn't in the title of the thread, so we must still deal with people (most of whom own none of the above vehicles) who insist that certain models are faster/more powerful.
In the case of the Firehawk, it's possible that a coupla mods done by SLP do the intake and exhaust might make a wee bit of power, I saw a dyno sheet that supported that. I don't think that those differences should amount to 35 hp, though (345 rating vs the Z28's 310).

RE: LS1
Yes, the LS1 lowdown. It's the Gen III GM V-8. 346 cubic inches, 5.7 Litres of power.
1997: The LS1 was put in the new C5 Vette, packing about 350bhp.
1998: The LS1 stayed in the Vette and was also put in the slightly modifed 4th gen Camaro/Firebird. It also spawned 4.8 and 5.3 liter truck versions.
1999: Kept production in Vette and Fbodies.
2000: Same as above, still making around 350bhp on ALL LS1-equipped models, no matter the manufacter rating. Only difference was a cored rear cover oil passage.
2001: Addition of LS6 intake which bumped power up to around 370bhp on ALL models. All Corvette Z06s came with the LS6 block which, unless I'm mistaken had the LS6 bulkhead vent windows in #2, 3, and 4 bulkheads, which eliminated need for 28.5mm drilled vent hole.
2002: Same as above. Final year for Fbody production. LS6s got power upgrades to 405bhp.
2003: LS1 in Vettes, LS6s in Z06s and CTS-Vs. Block was converted to all short head bolts and greater step from cam bearing parent bore to cam bearing bore with no change to part numbers.
2004: Same as above, except now offered in Pontiac GTO.
The Gen IV V-8. LS2 364 cubic inches, 6.0 litres of power.
2005: Offered in Pontiac GTO, C6 Vette, SSR, and truck applications. 400bhp. Short head increased-step cam bore block design, with 101.6mm cylinder bore diamteters, low mass block and main cap design.
2006: Same as above with the addition of the LS7. 7.0 liters, 427.8 cid. 530bhp. Ownage.

I outrun 2 LS1 Z28's the other day in my Si y0, but this new kid with an SS says he'll outrun me. What do you guys think? Do I have a chance against the SS?

Oh, and I think 370 at the crank is pretty generous, 345 or so would probably be more accurate.

Well, if they're pulling (mind you, I'm talking about the '01-'02s here) 315rwhp minimum with a %15 drive train loss, that is 370bhp.
