Highest Stock LS1 #???? Is this BS? Guy at work swears up and done his friend with a 02 WS6 made 360RWHP when he 1st bought his car, no bolt-ons, stock down to the freakin filter. Now I know some LS1's run strong but Damn!!!! 360rwhp bone stock, its a little hard for me to believe it, im thinking a LS6 cam swap or something, oh yea this was a Auto?!?!?! Show me proof (dyno sheets) and prove me wrong
you. Never heard of stock #'s close to that high.

Ah, well the guy did not say if it was corrected, and what kind of dyno was it?.....
On a cold day you could see 20more rwhp uncorrected vs. SAE. I see 28 difference all the time in the Winter months up here but, I'm also making 450ish at the rear to see that number. .94-.95 SAE correction
....
I have seen a **** ton of LS1's on different dynojets and none made more than 320 SAE stock(manual cars) and the lowest was 308 SAE. A friend had a Fire Hawk with the Dual/Dual Cat back and SLP lid from the factory.. We never did dyno it though and I have heard they dyno somewhere in the 330ish range (SAE). Even with a very high dynoing LS1 and a non corrected (Winter month) dyno, 360 is still hard to swallow....

My friend dynod his 01' M6 with just the free mods at the time, which included ported maf, FRA and true dual exhaust and it put down 345rwhp and it ran the times to back that up also. In roswell, nm which is at an elevation of 3600 ft with a density altitude of 5000 ft give or take a little he ran 12.7@111 on drag radials, his is one of the very few that I've ever seen do anything like that. It is a true freak no doubt.

Unless GM by mistake installed a LS6 engine in his car... There is no freaking way he would dyno that high stock. Hell my car with LID, LT's Headers and Catback didnt dyno 360rwhp.
