how much boost stock ls1
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.

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

Its on or around 8 psi.
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

Mine were fine after 10 psi on the stock longblock.
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.
