Not Jenetty but imho that is the top end of where I would take one. And I would probably keep it down around 700whp on E if you want some longevity out of it.
SBE LT1's are not going to live long @ 800whp. 600whp on pump 93 or 700whp with fuel system upgrades on E is doable. Meth and E @ 800whp can be done but it's getting dicey. Re-gap the rings then I could see sustainable power above 800 being made.
The LT1 has tight ring gaps so it's not as boost friendly as a LS3... Being stronger or not is a Moot point. LS3's have routinely made 900+ whp on boost. It was GM's most boost tolerant Aluminum block NA engine to date imo. They have enough ring gap to allow it. GM went to even tighter ring gaps on the NA DI engines to help control oil consumption and blow by from the high pressure fuel system.
You can install a cam to bleed off some dynamic compression and that will help raise the HP and Octane wall about 50whp, but imho it's not worth tearing into a LT1 for a cam swap and not doing drop in rod/pistons with it. The engine has to be torn down to the short block anyway.
