More Cubes or More Boost?
Yeah 800chp absolutely zero issue on any gen4 stock LS (LS2, LS3, 2005+ truck engines, etc). The stock crank is mega strong, some say better than some Chinese forged cranks. Blower 376 vs Blower 415 Im not sure you'd tell a difference, I think you would if it was turbo though. The main benefit of going more cubes is you need less boost so you can theoretically run lesser fuel, probably not enough difference in boost/displace at same power to make a difference in reality.
Watch "Richard Holdener" videos on YouTube and the video up above, you'll be shocked how durable the current stuff is stock, I grew up in the 80s and stock stuff was absolute 100% garbage compared to the stuff now that comes stock. Back when aluminum blocks and 6500rpm was exotic. I think its part of my obsession with aluminum blocks...flipping through Chevrolet Power catalog you could BUY at the dealership and seeing the $5k alum bbc blocks....$5k was a lot more money back then!
You'd definitely want to do a cam and dual valve springs if you get the stock LS3....you can make 500-550 before the blower, then once you put the blower on you don't need much boost to get to 800. Stock lifters, pushrods, rockers are fine for 800chp and reasonable rpm (under 7k maybe??)
Keep in mind Im one of 100 opinions and people are going to stop saying much now that Ive had verbal diarrhea this long and don't want to argue. There are lots of way to 800chp these days, luckily!

Thanks for the help Hank. I am going that route with the stock LS3 and bigger cam. The stock heads it comes with are good? And it’s okay that the compression is 10.7:1 to run up to 15psi on?
But if just on 91 or 93, I think those guys stay around 8-10 psi, something like that, need a spot on tune on pump gasoline no matter what engine you use. Torco/Boostane stuff really does work.
As cheap as DART LS NEXT SHP blocks are I wouldn't waste my time spending 1000 dollars on a ls3 block. I will take the weight penalty for priority main oiling and much strong block any day of the week.
No on is, the sleeves get thin, if you have a bore issue you are getting a new block cause the sleeves are thin. The large stroke pulls the piston out of the bottom of the sleeve and can cause piston rock.

750 FWHP is easily doable. Ryan on here Did new bearings and re-rings gapped for boost with a Summit Racing Ghost cam, LSA blower with a 2.5” blower pulley and some home snout porting and he got OVER 600 RWHP. His engine had to out over 750. FWHP. He built a thought out but simple package the works.
I personally.would do a 376-15B with a LSA based 2650. Just be sure to have a built trans, driveshaft and rearend. I’d toss on a Holley Terminator X to control it I’d drive it with the stock can for the. First season the cam it the second season just to feel the difference

I got all hot and lathered up to buy a $4999 LS3, called a bunch of places, all on backorder! I think the impending military invasion of Ukraine by Russia is dependent on them being able to finish converting all their tanks to run on LS3s what is going on with the LS3 shortage!! Maybe the tree humpers and Greta are buying them and grinding them up to save the planet from carbon emissions. How dare YOU.
Anyway I saw someone say that they come with solid intake valves, so thats interesting, not sure if its true, but I don't see that they are specifically L92 or LS3 heads, so who knows.

I called KarlsKustoms, EdRinke and Pace and two said late Dec and one said sometime in Jan, one or two said to get on the list now though or you'll get yours later, so I was like o.O
Watch buying it from Summit they'll prob charge tax no matter what Im wondering if any of the other places won't.
This is the cam I'd get if I was getting a new one, pretty big cam, sounds good, but very little overlap.

The one I have currently in my LS3 with 2650 is this
https://www.summitracing.com/parts/CCA-SUMLSGT108. Thats a good LS3 cam but probably too much overlap to be optimal in a PD deal, but seat of the pants it is amazing.
You'll need dual springs regardless of what cam you choose unless you stay with the stock cam then you could get away with Pac beehives.
