how much boost stock ls1
I cant find anything through search....how much boost can I SAFELY run on a 100% stock LS1. Im considering going with the remote location sts system. The car will be daily driven. Aslo how much boost can the ls1 block handle? At what point will the block just crack? I know I'd need to go with different heads and upgrade alot, but how much boost can the actual block handle? Thanks for any input or even pointing me in the right directions.

Your block will not suffer any damage under 1k rwhp most likely.
You should be worrying about the stock pistons which may begin to crumble for most at power levels of 500 rwhp and up.
This is assuming a competent install and spot on tune. In terms of boost that is about 8-10 psi on an otherwise bone stock LS1.

So lets pretend that 1lb of boost = 25hp. Your telling me that I could run 25lbs of boost and my block would be ok? obviously alot of other things would not be ok but my aluminum block isnt gonna blow to piecies? Other things take into consideration of being able to run 25lbs of boost I do understand that though.

But thanks for the info everyone, I've decieded to build my LS1 for as much boost as possible before upgrading to more cubic inches if i'm not satisfied with the output.

then theres the rods.
your crank and block can take over 1000hp without issue... over 1000, things might start to wiggle a bit, but noone yet has broken an LS1 block from too much power... they have however started to see stuff move around a bit over the 1k mark.
this isnt a ford block, we actually have metal holding the two halves of the block together.. LOL

do you guys know of anyone that sells a kit for practically all the fordged internals i'd need to run high boost and not blow the hell outta my engine? Or at least a good trustworthy company that sells them?

Lunati & Eagle for rotating assemblies. Plus alot of other companies that make parts of the rotating assembly.
SLP, Extreme HP, Scoggin Dickey, MTI, Texas Speed, W2W, and Thunder Racing for forged short blocks in multiple displacements.
Check the sponsors, there are alot of GOOD deals. I'm thinking of getting a forged 383 from SDparts or Extreme

More often, at least in this forum and my limited experience, I hear about pistons taking a dump... Very often.
Of course, that is definitely a danger too.
