Anyways, Those numbers are awesome, I'm assuming no tuning, stock GM cal, no tricks?
God I can't wait for the 2009 Camaro, the "detuned" LS3 that will most likely go into it is gonna be killer.

It's a very exciting time for car enthusiasts. The LS3 looks like another promising addition to the LSX family. I can't see GM making the decision not to place this engine in the next Camaro...

How about the power under the curve ??

The 376ci engine really takes advantage of the 1 7/8 headers.

It's nice to see the new motor's putting out all the power in stock form

are you saying you tested 1 3/4 LG's against 1 7/8 kooks? I would expect the 1 7/8s to out perform the 1 3/4 headers on 376ci motor.....
me too except for this one circumstance where Lg put their 1 3/4 pro long tubes on a heads and cam ls7 and put down something like 611 rwhp and they were talking about putting on a 17/8th header and they said they like the torque curve of the 1 3/4 and thought they would only gain a few ponies up top with the 1 7/8th header.

If they said "one could step up to bigger headers like 1 7/8" and pick up a bunch of power or you could stay with our 1 3/4" and lose that extra power . . . " that would be the equivolent of business suicide
So regardless of the potentially high power differences between the LG's and Kooks on a bigger cube motor, it would be prudent from a business standpoint for LG to say the "difference" is minimal to say the least
