In this thread he has a vid of it doing 451 and there are other guys with bolt on LS6's doing similar power in the thread.
It's definitely not the normal build but these guys are thinking out of the box by doing crank scrapers (they're only like $300) electric water pumps, shorter belt routings with less pulleys, I think when he did 470 he took the belt off. Most of these guys posts are kinda secretive but if you get into enough of their posts you start too see where they'll post one or two things they don't wanna come right out and say. I think one of them was running a 16 volt battery for more voltage to somehow help. They have super optimized intakes on them and exhausts, light flywheels and clutches etc.

These are LS6's that they are doing it with so they're gonna do a bit better than a LS1. But still it's crazy what can be done when all the little details are covered

yeah the guy on CF.com i remember that one i dropped off the forum after my car went down didnt keep up

some great numbers, i never said anything in that topic we both have c5z's i was running his times when my car was just 400ish to the wheels, when i was at 440ish i was i was in the 11.4-11.5 area then at 475ish 11.2-11.3 but thought it can be his driving not getting better times, i feel if my car had a drivermod it would dip in to 10's. still hard to get my head around it since i did almost every bolt'on heads cam intake and his dyno was 30ish hp less, his times was what 400hp range guys and myself ran but again it might just be his driving

pulling the belts electric water pumps and all that i guess is good for bragging rights but not my cup of tea since i drive my junk, its like the guy who go's to the track strips 500lbs off his car leaves all those parts in the pits then tells you it runs xxx @ xxx mph but skips the part of it being gutted to run that lol

Even if I go ahead and provide flow numbers most of this will remain unknown. Would need people to actually dyno these changes on combos which unfortunately is going to be hard to ever get data for. I'm curious on the shrouding thing too as then why GM bothered to add the larger heads to their most powerful combos. Its kind of like why they did L92s on all the truck 6 liters when honestly a cathedral is a proven better choice. Probably between emissions and a desired hp number result is the muddled reasoning on why they did things the way they did. Considering the camshaft used in the LY6 and L96 is nearly identical to the LQ4/LQ9 cam short of it being a VVT grind I am sure its the 360 hp number that called for rectangles as not much else changed that would have increased the power number.
