Does the Darton-sleeved block have any advantages over the very pricie GM C5R block?

Any chance the prices will decline?

Yes. The Darton wet system replaces all the aluminum material surrounding the piston bores. They are also integrated with each other to prevent shifting. I believe they are ductile iron. Not sure on that though.

I never heard of the bores on a C5R shifting. The only advantage of the Darton sleeve approach is $$.

The Darton sleeves are stronger, and much cheaper.

The Darton Sleeves are stronger? I did not know this..

That seems strange, I would think if that sleeve system were so stong that more tuners would use it instead of the C5R block. I've also heard that particular system is more prone to leak - where as a C5R block wouldn't.

Only advantage of darton sleeved block is affordabilty(salesman speak).I doubt if the C5R will come down in price anytime soon.I would say it's more likely to go up in price.I have complete confidence in my ARE updated resleeved block.

Leo:
When you say the Darton is more apt to leak are you referring to water jacket leaks, oil leaks, or compression leaks....?

In my opinion there isn't enough of the NEW Darton sleeved blocks out there yet to know their true durability. I have more confidence in ARE's resleeving than anyone else's so far. They too use Darton sleeves but they are custom made only for ARE. I haven't heard of a sleeve problem with an ARE block in probably 2 years and some guys are running ~1000hp with them.

In the early days I heard of problems finding a perfect C5R block, which is scary for the money they sell for, but lately I haven't heard any more bad stories about C5R blocks.

...lots of posts here about dropped dry sleeves ...including the newer work...

...IMO, too much risk - for me

I may just to an all stroker...???

I have to wonder just how many leaky Darton-dropped sleeve motors are really out there.I would have a big cube motor right now if not for the worry on those issues.C5R block not in my budget.

Lets get the C5R block down to $3000 and they would sell a ton of them.Dreaming

You have'nt heard this about AREs blocks though.I'm getting mine put together right now.I would'nt buy a resleeved block from anyone else except maybe LPE.You're reading posts about non ARE blocks.Wades car makes over 1000 rwhp and stays together.

I thought the dropped sleeve problems were limited to dry sleeves made by Darton and others...

Aren;t the wet sleeved Dartons LOCKED so that droped sleeves can;t occur?

the only isue with locked Dartons is price (about $3.5K with a cheap $600 core) right?

robertbartsch

the difference in cost between the Darton wet and dry sleeves is not great about $500...

...so, if your inclined to go this route, it seems silly to go dry; right?

I've heard of block problems from all camps including ARE. If I were building a big bore I'd go darton wet or nothing, the C5R is just too expensive.

I called Joe Prince concerning this. I inquired about a 388 all bore and the options for the build. He told me that he build me a forged bottom end (stock crank) with the Darton wet sleeve short block for under $5k- including cam and chain.
I don't see how there would be any other option.

I'm holding my breath and waiting to see if the new 6.0 C6 block will be backwards compatible with GEN III. I heard the internals will work in the new block, but the new block will have the knock sensors mounted on the side of the block and the crank position sensor will be in the front cover. The crank position sensor throws me off though,,,,if it is going to be on the front of the crank I don't see how GENIII cranks will be compatible.

robertbartsch

realy? is this the bigger engine for the Gen six corvette?

when will it be born?

robertbartsch

Lingenfelters wet Darton block is $3.5 K. ...add pistons at $500, Rods at 500 and your about 4.5K, cam at 300....

So is the Joe Prince motor a deal?

Very interesting info, I'll try to ask around with my contacts about that.

C5R is the strongest block, it's a production block with thicker webbing but they cost $6000.
