I am oblivious but I still think the old sbc make more power I have yet to see an LS engine make
800+ horsepower in N/A form like the sprints do. Some are way over 900 these days with a 3.85 stroke.
To be fair, these engines cost about as much or more than any of us make in a single year but any way you slice it, the numbers are impressive.
Oh, they are lighter too when you look at the weight of cranks and block. The warhawk block is 130# and a Rodeck or Donovan SBC block is right at 100# The cranks are lighter too.
Dont be rude but am I missing something?

Second, I want you to google School of Automotive Machinist. They made right over a 1000hp with an LS, all motor no power adder. Yes they have a 4 inch stroke in there but that is only .15 more stroke compared to what you posted.
The weight issue is non relevant. Knowing an LS block is a deep skirt design and the mains are a 6 bolt design is most likely where the extra weight comes from. Just look at an LS main cap and a SBC main cap.
As for your last sentence, you are just missing a little knowledge.
Just get in the engine and advanced tech section and you will learn what these engines are capable of.

There are also quite a few LSX engines now exceeding 900HP and some have also surpassed the 1000HP level.
Give it another year and I'm certain there will be many more 1000+ HP LSX engines

The smallest I know of with inline valves is 39x cu.in. that broke 900 HP. I also know of another 39x being built at this very moment that may break 1000HP with inline valves. MCP in N.J. has built both of these. He has also built a couple 460 inch Canted Valve Nitrous engines that are 1000HP in N/A form.
I'm sure their are some others that I'm not aware of at this moment. Maybe someone can add to this.

803HP (flywheel) @ 6500 RPMs - not bad for a motor that's going into a street car, granted it's a little larger than a 410.

I think you should do some more research on this. The K&N Pro series car (formerly camping world East and west series) use 850 hp LS style engines with a front drive distributor set up. The big difference here is the original sb1 small block chevy has over 50 years of hotrod technology R and D in them. The LS motors have only been around for 14 years and the aftermarket didn't catch up and start really supplying parts in the last 5 or 6 years. Hell look at the Jegs catalog and try and find some LS pistons or rods. There is only one or two companies making 1.8 stock replacement rocker arms in a true roller style. The no longer produced by Ford 5.0 engine still has more pages of performance parts in Summit and Jeggs than the LS style motors. Think about this, There was never a sb1 stock head that would flow over 320cfm much less 353 cfm like the ls3 head. I mean come on the 6.2 truck motor makes 445 hp stock. No sb1 ever made that kind of power stock and pass emissions. I don't even think that any of the solid flat tappet cam 350's made that much. Also there is not a bone STOCK sb1 motor combination that could produce 800 to 1000 rear wheel by adding a turbo and a camshaft. Hell the sb1 blocks would crap all over themselves if you tried that without splaying the main caps and doing a half fill on the coolant passages. The LS motor is the most responsive motor to a camshaft change also. I will NEVER build an oil leaking gm 1st gen motor again for myself.
