Default carb'd ls1 database

I'm compiling a carb'd ls based motor database. Don't need any responses in here besides what's listed trying to keep this thread clean of any bs. If you have questions PM the person who posted so this stays on track. Doing this in case we ever get a carb forum, would like to get a bunch of research out of this.

It made 498.8 HP @ 6000 rpm and 465 TQ. The hp curve is going up sharply at 6k, my guess is it probly makes around 525+ @ 6500 and up. This is flywheel HP/TQ so im curios how much i will lose to parasitic loss.
