Alot of justification for a C5R block can come from incidentals. Lets assume that MTI will honor their warrantee on whatever shortblock you buy from them. *IF* you dont live in TX, the cost of either paying to R&R the engine or ship the car back/forth to MTI can become significant. I had a dry sleeve motor which was replaced on warrantee with a wet sleeve motor for the cost of the sleeves. If you add the price of the original dry sleeve block, plus the core, plus the wet sleeves, plus the tranportation of the car back/forth to TX... I should have gone for a C5R block instead. Would I go to MTI again? Sure. I would have bought a C5R block in the first place though. I only have 700 miles on the current engine, but its using oil in huge amounts (I think one of the heads is cracked...not an MTI issue). I cannot exactly sleep soundly at night as if I had a C5R block. Was I told that the Wet-sleeve process was a perfect science? Sadly I was. But then again I was told the dry sleeve process had been worked out too. I'm going to learn one of these days. Either way, I don't have many miles on the car :-/ and I'd really LIKE to move to a 4" stroke. Wisely, I went all-bore thinking that the block/sleeving process could be trouble, and I wanted to get it sorted out before moving to the bigger stroke. I also don't need to spend the big $$$ on Lunati billet stuff, and last time I checked, it was all MTI installed.
One of the issues at play here is that MTI has been very good to most of us, even if there have been sleeve problems. MTI rescued me from ARE back when Jeff was the shop foreman, and I was ready to kiss their feet. I have had nothing but fantastic dealings with them on every aspect of the engine, though I almost *always* have to talk directly to Jayson for the whole/real scoop. Rick (the newer foreman) has treated me very well too, and I while I was told that these sleeved motors are very reliable, I have always had reason to doubt it. I did not go blindly.
If MTI would only admit to their loyal customers that the process is not perfect yet, we would probably still go for it... albeit knowing the risks. I suspect that they have always felt that the perfect process is the one they are just now using... I was once an engineer of consumer items as well. Its easy to believe you're just turning the corner.
As a consumer however, I am far more afraid of what I don't know than what I do.
MTI continues to fix problems of mine that werent necessarily their making, and in every other aspect, especially cost, they have exceeded my expectations. I understand that Steve at Race Engineering is the inventor and offers the blocks, etc. However, I am a loyal customer of MTI's. But I should be honest with my friends and admit that the sleeve process has not been easy or straight forward. Go... but go knowing.

I have to assume from what your have written, their (MTI) customer service was not getting anything done? I had a bad experience with them also. I gave up, after they got my money they would not give me the time of day. I tried to warn a few others and the MTI cheer-leaders beat me down with the "it was all your fault crap"....
Oh well.... Thanks for not playing the silent save my ego game and letting the rest of us know.....
...good luck...

The reason people are slow to announce some kind of failure on this board (or others) is the countless train of bull$hit bandwaggoneers who love to come in and bash any vendor they don't use. If you want to talk about ego, those are the folks who are puffing their chests because they were "smart enough" not to use said vendor. Pretty soon you have 75 posts of people saying how crap a vendor is, of whom one has an issue, three have bought intake lids, and 71 don't know WTF they are posting about.
Appreciate that those of us who have been around here far longer than most (all the way back to F-body IRC chat rooms in the 90's) know well how out-of-hand a "problem" post can get if not properly bracketed, prefaced, and footnoted. Given then that such a post can be tantamount to starting a war, most of us have learned that we can get our problems dealt with far more quickly, effectively, and cheaply with diplomacy.

Am I the only one having problems? Less than 1000 miles on the engine NO NITROUS! I'm so scared to put nitrous to this paper shortblock. I'm thinking a 402 iron block would have been a better choice. MTI gave sugestions on how (I) should repair the block or they said I should upgrade to a C5R? 
I didn't know you needed a C5R shortblock just to hold coolant. 
Anyways, has anyone else had any problems?

in short....yes.....your the first person I know of with this problem....

I find that hard to believe... given how many they have made.
Most of us know about the dry sleeve issues... but even Steve at Race Eng. only knows of a few Dartons that havent worked out... MTI or not.

FWIW, I know why the MTI Darton blocks have issues. I'm not going to post it, but let's just say it is not because of a design flaw in the sleeve.

This is all like arguing if Superman is stronger than Spiderman. I don't know anyone here that is capable of max'ing out either block design, properly installed.
I'd be happy to let this thread turn into that discussion, since I bet LASTLS1 and David Coates will work something out.
But in Ferris's words;
"The Europeans could be Fascist Anarchists... it still doesnt change the fact that I don't own a car."
