It very could be that the Darton sleeve was machined down to much from Darton themselves. Maybe MTI did it, I dunno. And it going bad around 1k miles is strange, unless I missed something in this thread. From what I gather in the first post was he had some miles on it before it started. But you'd think it would happen from day one or alot earlier for poor machined parts.

Why take a gamble or risk of this magnitude? Just my $.02

Crager, are you saying the MID blocks CAN'T take a power adder of nitrous or turbos??? So they are good for 500hp NA only?
I beleive MTI knows their **** and was machined right etc... Maybe call and talk to Jayson again and explain the situation..
I just think the problem with MID blocks is there is SO much crucial MEAT taken out of the block, that there is a great chance something WILL move or shift eventually. It has to! The whole deck and internals are removed, kinda a 'can-opener' effect. All thats left holding the deck together is the head studs.
The ARE Big Bore blocks leave all the crucial meat behind the original sleeves which is also main strength of the block, PLUS we don't hit water, so there is no way it
will leak. Our sleeves have special steps and install instructions so they CANNOT Drop.We have the biggest 'sleeve lip' in the industry. ALso a few other sleeve specifics I can't comment on.
We don't care if you use nitrous, turbo, blower... We HAVE tested our Big Bore 4.100 blocks to nearly 170mph.
One last comment, when others jump in here, please talk about LS1 or LS6 Blocks ONLY. I don't care about Honda, Viper or Ecotec motors.. They have absolutely NOTHING to do with this conversation. So why compare a totally different block casting??

I've seen a Procharger blower (I think) on a Darton block and it made around 800rwhp. There is too much that could go wrong with any kind of power add'er and it could grenade the block. So they don't allow power add'ers for warranties.

Craig.

First off. Speed inc Dynoed the car the night before the street drags. NO POWER ADDER! That night it happened I was racing at the track for money. Motor only. There has been NO POWER ADDER on any MTI block I've had. Prove me wrong by ANYONE OR ANYWAY and I'll pay you 10K!!!!! I believe Tom from speed will vouch on the power adder issue. It's a cop out! That car made 5 track passes N/A! Three one day and two the night it started leaking again. I want to spray. That was my intention from the begining. But I want to make some track passes N/A without LEAKING COOLANT! Also I already made a statement! ANYONE show me how (I) caused the problem and I'll buy a new C5R block from them. As far as the miles, I don't know. Maybe because the car had true dual dumps with bullets. It would rattle the windows out of your house! So driving hard on the street wasn't going to happen. ( I bought new mufflers)! Bottom line three motors in a row to the same person! N/A. You kind of see the pattern??? If I would have sprayed the car this wouldn't be a lssue. Those motors have never seen nitrous! I don't trust them. I would rather have a rock fight in my glass house! It would be safer than pushing one of those blocks. Thats why I bought a new 408 iron block from LME yesterday! 
It's a shame you don't know me. My word and reputation would far exceed your wildest expectation. I'm still going to get the Darton repaired. It will be my back up motor until I decide what to do with it. I don't want to sell it and someone have a problem. I guess after I run my iron block for a while, I'll put it in my car and run it for a while to see if it's ok. Otherwise I won't sell it. If it happens to run strong and DOSEN'T LEAK! I might to spray it, if it lives I might keep it. 
Thats what I wanted in the first place.

I couldnt justify 6500 for a C5R block when I can get a 4 inch LS2 for a FRACTION of the price.
For a street motor a C5R is a total waste of money even at 800RWHP.

But for LASTLS1 to feel ripped by MTI so he goes to ARE would be... ironic at best.
Dave, you need to start "Dave's LS1 Shortblocks" and do this without the baggage.
BTW... Andy... If you are interested in selling the rotating assembly from the 427, or even parts such as the pistons (no use for them in a 408), let me know. I need to convert form 388 to 427 soon (since my bottom end seems quite sound).
Thanks,
Chris

HILARIOUS.
I don't see the big deal I guess, none of this falls under MTI's written warranty, so they are off the hook. It sucks, but you gotta read the fine print...that's life. An LME 408 will be awesome, good luck to you!

Even though I've approached Andy about this off line - I'm going to state MTI's position on this so everyone can be aware:
I've asked Andy to contact me after Steve at RED has a chance to look over the block and then I'll work directly with Andy to try and satisfy him and turn this situation into something that he's OK with.
No one person or business is perfect, mistakes do happen. We like everyone else try to keep them to a minimum because they cost money - both in customer goodwill and actual monies out of pocket, not to mention time and aggravation for everyone involved.
Sincerely,
