alright im contemplating building my stock motor or getting the gen 3 zzp block and building it. building my stock block would be alot cheaper but on the zzp site it says that the darton sleeves destroy the stock lsj block? is that true? has anyone had good results using darton sleeves? my goal is 600whp by next year. once/if i hit 600whp, ill probably want more so will the darton sleeves be fine? 700whp give or take will probably be my end goal

 

dartons will not destroy the block

 

PM Mrbelvedere if you're looking for the best sleeves out there

 

alright thanks for the info. should save some money

 

do you think the lsj block with sleeves from Mrbelvedere, zzp 4340 Connecting Rods and pistons will hold 500-700hp?

 

I think zzp means the block strength can be weakened when installing Dalton's. Especially if the machinist doesn't know exactly what they're doing.

While Mr.B's sleeves haven't been tested to failure it will handle anything most can throw at it.

 

yea im not 100% what zzp was saying. if you type in google darton sleeves lsj, you will see 2 links from zzp (they dont work) but under it you can read "When breaking people thought the sleeves we're weak so they installed darton kits. Problem with Darton sleeves is that they destroy your block. The block ..." you cant see anything else said besides that.

 

I know the link you are talking about. The block takes modification for Dayton sleeves which can potentially weaken the block. There are only a few actually authorized dealers that can do darton sleeves properly.

Mr.B sleeves or a Gen 3 block would be the way to go IMO

 

I sent the only block I ever had sleeved directly to darton and it wasn't any more expensive than any other place would charge to sleeve it.

The ecotec blocks have a LOT of material removed from them when being cut for the sleeves, which can weaken the lower side of the blocks and possibly allow more shifting or possible cracking around where the sleeves are installed. ZZP has articles where they cut open the blocks after sleeving and there were cracks spreading from the sleeved area into the main webbing.

 

wow thanks for the info

 

I know you're an "old timer" (not sure if you're still in the game or not) but i'm assuming you aren't aware of Mr.B's prices... You can get his sleeves and have him install them for just a little more than HALF of what the Dartons cost ALONE. God only knows what the machine work on them costs....

Not saying either is better than the other, just saying i don't think you're aware of the price diffference.

 

he wasnt trying to discredit mrb's sleeves, just sharing his experience with dartons.

 

I know he wasn't. I'm just talking about price differences. Nothing more, nothing less.

 

Then id agree, price wise, MrB is the way to go.

And a way id like to go eventually.

 

Smart man.

Mr.B can you sleeve the Gen II 2.2's easy or prefer the gen I and just run the head you need.

 

I can do both its up to you which block you want to run

 

Yeah this was back in '09/'10 maybe, in a local LNF. I've spoken with MR B and am aware of what he does now, just shedding light on the darton topic since it's up there.

Darton charged us $600 for the installation work IIRC, and yes the sleeves are fantastically expensive... but at the time it was the only option.

 

another one out there is Mongorat does good sleeves and a decent job of it with brilliant sunnen honing. I have no clue on pricing. Mr. B does great work no doubt. Like Joe says the OP was about Darton and thats what he was commenting on.

 

If i had a do over button would be mrB sleeved gen 1 with zzp girdle.

O wait....
