Freak Cars
Mine runs high 8.58-8.64@88-91 with a 2.0 60' there with diy ram air, muffler!, lid/filter, and a few degrees of timing. Most stock ls1s are in the 9s there (the 4 I've seen)
My brother's car with a dyno verified 359whp is a tenth quicker and a mph or two faster in the 1/4 than mine. He says mine is a freak.

Forgot to mention the track is backwoods and slightly up hill. The burnout box is a 10+ feet lower than the track and you have to drive up a hill to reach the relatively flat track and stage. There is another 1/8th pretty close by and everybody says their car is 3/4 second faster. Probably not that much but I'd say at least 2-3 tenths.
I like paradise though because it's cheap, close, and never crowded.
Here is a pic for reference though.

Of course he is also neglecting the fact that on the same dyno, the same day under the same conditions 2 different yet completely identical stock cars can have outputs varying over 20rwhp.

Get both on the same car and you had a "freak". Machining on the new stuff is so precise, these cars don't vary a whole hell of a lot from one to the next. Talkings thousandths here. Not nearly enough to account for giant leaps in horsepower.
All I can tell you is that we would have Dyno Day and I would see from 235 to 265 RWHP on STOCK LT1's, comparing M6 to M6 and A4 to A4 Not an auto to a standard. On LS1's we would see from 285 to 315 RWHP. again stock, comparable mileage...Thats just my findings/results so take it from there..Dyno variances? possibly, but that much of a difference? I dont think so. Also I have had a couple of the high horsepower cars at a different dyno, different town and they still made the same figures...
I had an 01 z that never saw a dyno, but ran 12.80s all day @109 w/ a LM2 catback. stock lid too. Auto car though
12.9 with minimal mods.. No freak
354 basically stock?? Thats FREAKISH
we put a lid and short-throw on it and she went 14.1 @ 111 on her 3rd pass in the car. eventually got it down to 13.4 @ 109 (1.96 60' but spun bad midway through 2nd..). it would run door to door with my 110 trap bolt on car on the highway and starting inching me at 120+. i managed to go 8.3 @ 87 with it 2 years and 40k miles after she bought it, but it developed a misfire on my best pass and ran the 1/4 out to 13.2 @ 104. i have since then tuned it up, added an ory and removed the air/egr, i am anxious to get it back to the track.
i'd call that a freak. bear in mind this was central indiana summer racing, da ~2500', literally full weight +her ****. we put like 500 miles on it last year haha. it is currently serving daily duties as the baby toter is down and i'm very lazy.
375/397 Iv also got a dyno sheet from a mustang dyno at Turbochargers.com here in houston showing 381/404
with the acception of having 1.8 crane golds in at that time.. whats really crazy is that I used to have the original ls1 that came with the car and had all the same bolt ons with the older version trex cam and only made 396/377 with a much shittier power curve and this ls1 is out of my buddys vette that did 305hp stock with a paper air filter before he yanked it to have MTI build a 427 for him. Thankfully he yanked it right around the time my original motor blew and I got the longblock! This thing stock is leaps and bounds faster then my old one with the trex cam. My buddy Kenny in his fox has raced both setups and he can attest how much faster this one is. GM's got some beer drinkin/hottroddin automotive machinists in there getting a kick out of trying to hide uncertain parts into uncertain vehicles! lol
Mods list when dyno:
01' vette ls1 with UNPORTED "241 heads" Could possible have the ls6 cam tho, think the later vettes got them slipped in when noones looking. but not sure, Iv never taken it out of the motor to mic it.
Ls6 intake
slp lid/bellows
free ram air mod
pacesetter LT's
Pacesetter ORY
manaflow 3in. exhuast(no cats)
6speedinc. m6
ls7 clutch
Ls7 flywheel
stock 3.42's
and no a/c belt..

had crane gold 1.8 rockers,ls6 yellow springs, and comp stock length pushrods in it on the mustang dyno run. I figured Id lose alot of power on it.. boy was I wrong!
