As long as your fluxcapacitor is fully charged it will support 1k horsepower!

ls2 iron blocks and ls3 alum blocks hold over 1000rwhp how much are you planning to make. I would use a ls2 or 3 block before a 7 any day

LS3 block is incredibly strong, just don't get it hot and 1000+ rwhp is possible. I'm building 832 at the crank with my 415 LS3 and have zero problems, well besides an LS7 lifter failing. :O

My buddy has made 950rwhp on a stock LS3 block/crank, forged rods/pistons, ported LS3 castings, stock LS3 intake with a GTS76 turbo (custom wheels in it).

LS7 blocks are supposed to have thinner sleeves..... Steve Demirjian at R.E.D. resleeves a lot of them even being N/A.

The LS3's have experienced some oiling failures when used on road courses. Probably not a factor on a drag strip. The stongest option you mentioned is the Darton sleeved LS2 block.

Just keep it under 88MPH.

What exactly is failing on these? Any solutions to the problems they're having?

Under 88 lmao!
My turn to throw a grenade.

The only problem their having is young guys not building them right and throwing parts together. Then coming here and not listening to reason or experience or blaming others.

Your foolish remarks aren't getting you anywhere very fast. And I fixed the problem with my engine very easily, which was a Barbell plug. BTW, I'm pleased to report Scoggin Dickey is making up for their mistake and I have nothing but good things to say about them now. So take your promenade of B.S. elsewhere.
