How much power/ factory block/forged internals
How much power will the factory block hold with forged internals?

I didn't want to go over 700 with 4 bolt heads, that's the real weak point on the LS3.

No he means the heads. Stock ls3/l99 blocks and heads only have provisions for 4 bolts per cylinder, limiting their resistance to cylinder pressure.
I am using 6 bolt heads on my 4 bolt block because they have a thicker deck to resist lifting. I also bought them because I will be using a 6 bolt block on the next iteration. I am over 1000 crank hp with my stock crank with forged rods and forged pistons as well. It is a centri setup and they are typically easier on parts. |

It's pretty amazing how much power the stock LS blocks are holding. The ARH/FARK Camaro made 1300 with a forged 416 and the stock LS3 block, but that really pushing it.

Plenty of people make 1100+ on 4 bolt heads. Good gaskets, L19 1/2" studs work wonders. Plus a lot of shops like to keep 4 bolt heads as a fuse. If it pings it will take out a headgasket before a piston if you are lucky.

You need at least 1000 RWHP for internet racing.

Seems like boost is the issue with lifting the heads.. The magic number is between 22-23 pounds before it starts trying to push water.
