L33 Aluminium Block Power Handling Hi All,
I have a complete Gen.3 L33 and I was wondering if it was built using a forged/steel Crank/Rods/Pistons with ARP bolts would the block hold up to 1000bhp (flywheel) or would it flex and wreck itself?
Does anyone know of one of these blocks being used in this sort of build and did it hold together?
Many thanks.

I'm in the U.K. and we're not as up to speed with LS engines as you guys in the US and the L33 is particularly rare over here, it took me almost three months to get mine imported. Parts are just as hard to come by so I need to be certain about what I'm doing as a second chance resulting from a mistake will take months to sort out.

L33 blocks are the base for a lot of serious builds. ERL used them as their base to build super deck blocks that have been WELL beyond 1000hp but as they sit box stock 30lb builds have been done with success. The 4 head bolts become your road block at that stage

Thank you, please excuse my ignorance but what do you mean by 30lb build? Someone else mentioned 20lb. Over here in the UK we talk about psi for forced induction engines.
Many thanks.

My info is a suggestion, a range, not very exact but it sounds like Krazy4 knows better and I always want to learn more so perhaps you could be so decent to write up a point by point explanation to inform us all on the limits of boost on the L33 and where their exact peak psi/power levels are? Would save us all a lot of time and if its good we could ask the mods to make it a sticky
thanks krazy4

the block is strong enough for sure. invest in some decent head gaskets and studs. the small bore size has a very beefy liner, don't be tempted to bore it out, plenty of good pistons out there from diamond and wiseco and others.

The article linked is about Jon Capizzi's Mustang. I know the build well, his first turbo (S485) now resides in my Camaro. He checked all the ring caps,, they were opened to .025. The tuning window with stock pistons and heads is smaller, so when you ask around you find that folks run less timing.
I have an iron gen 3 5.3 in mind, all stock including the 799 heads, and my plan over the winter is to source an L33 and put forged pistons and rods in it for 2019.

Anger? not one iota of anger, a little bait to see if you would write up a sticky worthy article where perhaps I and everyone else might learn something new? Guilty 
the sarcasm thing doesnt work for bupkiss over the net. I have no idea who you are, and maybe you know boat loads that I can learn from so I threw bait, I get guys posting up all sorts of good info that way occasionally. Or maybe not, how could I know? If you did have bucket tons of previously unknown info to share my earlier post would have shaken it out im sure. Seeing as your engaging in some personal retorts me thinks you know equal or less than I. In which case the previous post also speaks for itself
more bait lol
