Sounds like a good build. Sleeving makes for easier rebuilds in the future. Well you don't have to shave the original block anymore anyways. But that looks like a bitchin setup you got there... I thnk I speak for everyone here when I say we want timeslips when you hit the track. Good luck dude.

it helped on the ms3 mzr, I think zzp said it helped some too but maybe not at the cost of porting it. But what do I know, I'm low on coffee and tired as hell with no memory what so ever.
i've know they've been pushed there though lol

and im confident with the block as far as i can push this setup. Eventually when i do a ZZP 256 setup i still do not think i can hurt the block, Im not too concerned.

Think about what you just said... how can a block be good up to 1000 hp yet the sleeves are only good for 400 bhp?

I did think about what I said.. hense me saying it... so relax. A block rating is completely different than a sleeve rating. The gen 2 block is VERY strong, however the 2 weak links in the bottom end components are the sleeves and the pistons. Unless these numbers given directly from GM's build book are somehow wrong. I very much doubt that though...

ehhh if anything I would call it more "conservative" than misinformation really. I mean like you said, the sleeves have been proven to hold quite a bit more than 400bhp, and the pistons.. well those have been sort of hit or miss depending on the setup and tune. I think that GM just rated the componants for a "safe" build more less.

I have not heard of one person to blow up the sleeves on an lnf block or even an lsj.
I really do not care what gm bean counters say. It takes alot to **** up a sleeve, usually over 1000 hp, and im not gonna be anywhere close to that.
I don't think the sleeve will be a problem even after a turbo swap. and if the sleeves were rated to 400BHP then why wouldnt every tuned TC be blowin sleeves?

however.. that being said.. people are using lnf blocks as a "cheap" alternative to sleeving the block.. soo what does that tell you
and john there actually is misinformation as well as being "cautious"

You ever figure out what you're doing with your setup btw?

Well unless these LNFs are freaks of nature... A sleeve won't magically explode. Properly installed sleeves will take WAY more than 400hp... plain and simple. I was merely suggesting them because every time you replace pistons you have to grind into the cylinders to hone out the ring wear. A sleeve just prevents this because you can just remove the sleeve.

As far as machining, i have no idea what the tolerances are. The guy that built my brothers supra motor the second time is building my motor, and that car is pushing 900+ to the wheels and doing 213 in the standing mile, so i have faith that he knows what he is doing, but im hoping not to resleeve.

honing depends on the size of piston he has, normal is .10 or 1/10th of the bore of the cylinder. its basically to restart/refurbish where the pistons sit.
the original pistons made a groove, and now that groove needs to restart.
if he wants bigger, .2 or .3 im sure he has to re-sleave the block.
(ive never looked into rebuilding the lsj, or lnf, this is all speculation)
the rods have to be balanced. that means that each piston and rod weighs a little different and they have to be balanced to flow perfectly together otherwise you have a rough idle motor and its just not good in the long run.
most honing costs aroudn 200 dollars. new sleave install will probably cost a little more.

this happend to me and i had to sleeve my block... ring land got some pretty good scratches on my cylinder wall that if i bored out the walls would be too thin...
