As much as I detest quoting magazine articles, there are two that come to mind:
October 2014 (sorry, can't find a web link to the story online other than
this, but it leads to a dead link): CC builds a turbocharged 454 pulled from a Suburban, added a mild HR cam and a pair of Brodix heads and winds up making 950+ HP and over 1030 lb.ft. at just over 19 psi. When they added race gas it made 1200+ HP and 1300+ lb.ft @ 29 psi. Note this was going through a single plane intake, an 850 Holley and still using the OEM short block--iron crank, cast pistons, and stock rods. All they did was open up the ring gaps. Disclaimer: IMO they're nuttier than squirrel sh*t making that kind of power on the stock bottom end.
2003:
Import Killer Using a 454 HO crate short block, they added AFR heads, a Crane hydraulic roller, and a Vortec supercharger. On pump gas it made 950+ HP and 750+ lb.ft.
Both are admittedly old school approaches, but the power is still there. I wonder how civilized either of these could be with the addition of a modern EFI system.
Don't misunderstand, I'm a big fan of the LS platform, but I'm not ready to throw in the towel on the beloved rat motors just yet.
