New Build HP Numbers
I have a 2010 C6 GS Corvette.
I recently blew the engine due to my piston rings breaking in a back to back hot lap race. Before I had an LS3 with 1 7/8 long tube headers and A&A Si supercharger that made 623 to the wheels.
Now I'm about to purchase an aftermarket stroker LSX/LS3 block with a displacement of 451ci and I've also upgraded to a A&A Ti trim and methanol to the my car. With the bigger displacement how can I get a good estimate of the power I will be making. My goal is to get to min 800rwhp and 1,000hp max as I don't want to put roll cage in my vette unless it's super stealth. I saw a demo with an LS7 making over 800 rwhp on 5lbs of boost with the Ti trim. Is there anyone running the 451ci LSX on Ti Trim and if so what hp numbers are you making.

I'd probably cut back on the bore so you can get enough head gasket between the cylinders, otherwise you will probably torch head gaskets, the block and head.
Just make the power with boost, a stock bore and stroke LS3 can make 800rwhp
