      lots of shiny stuff.
      I want to see the armor coated crank when it shows up.
      I found a link where a back to back test was done. I don't really trust these tests, but it looks good.
      Eagle also offers a much better warranty when they do the armor coat. Not that it really matters in my build.

      thing about warranty is, sure. they will cover the part that failed, and not the parts it took out in the process, and labour.
      yea, im being a grump about it, but hey, its true

      Its absolutely true. lol.
      Besides, assuming the thrust bearing stays intact, there is no way the crank will break before the block.

      They must make great profit on each crank they coat. That's not being a grump, that economics. Dimas recommends it, so I went with it. The last thing I want to hear from him is "I told you so...."

      Wow. Great sounding build so far. Glad I found this. I love the converter choice.

      I thought I'd share what I'm pretty sure my torque converter was doing. This video is pretty awesome, illustrating what high pressure at the tc does.


      I don't think it was ballooning, I think it was the partially crimped cooler line creating excessive back pressure pushing the tc towards the flex plate.

      I would be interested to know how much movement that was in the video.

      From the looks of it at least .025

      Trouble in paradise.
      The donor block from Tim suffered a thrust failure also.
      Going to have to find a block.

      I wonder what caused this thrust bearing failure? Is this the block from the green truck that Tim bought and sold?
      Wonder if he had an aftermarket transmission cooler?

      Dimas said he wants to proceed with shot peening and see what it looks like. He said he won't charge me for the machining if it still doesn't look good to him.
      A dart block is $3400 cad looking at summit. I'm sure Dimas could get me one cheaper, but that price gives me a ball park figure. That is a substantial chunk of change.

      What in the world is going on up there? I don't think the blocks like your cold!!

      Seriously tho, that's just crazy the replacement has the same deal.

      The dart block might sound expensive now, but in the long run, it just might be the best thing for it.

      We wheelers, spend crazy amounts on off road parts just to be able throw the abuse at it again, and again. Like $5K on a transfercase, or axles, so the same principle applies here. Peace of mind, is priceless. Do what ya gotta do, and get to enjoying your hard work.

      Yea, I'm so deep in I will do whatever it takes at this point.
      Problem is, there is nothing to stop me from F'ing up the new block with another thrust failure. You know I'll be popping the belt off and checking thrust after every drive for the first while. I guess I better invest in a dial gauge.
      To add insult to this, its another delay.
      I'm guessing Dimas is hoping that an align hone cleans up that surface. Its a piss off for him also as he was doing two sbf's together to save equipment setup time.

      this pisses me off as well. i knew cellys motor was starved for oil, the bearings did see better days (one rod almost had nothing left for a bearing) but the thrust didnt look too bad. it had wear on it, but nothing like mine or yours had, thats why i gave it to him to work with. surprised he didnt say anything about it, i was there today getting the intake/valley pan from him but maybe he wasnt working on it just yet.

      How would you repair that? I'd think you could take material off a block, but can't add material.

      Mill it down, and a larger bearing cap?

      I think that's it also. I think you can do this if you have a undersized crank, but I don't think there are bearings available for an undersized block. If this is the case, then I'm out of luck.

      I should know by Thursday if that can be cleaned up. I don't want to slow things down, so if on Thursday the news is bad, and either Tim or myself have not found a block, I'm going to give the go ahead on the dart block. It is confirmed as being in stock at the Canadian supplier. I just want this build to get moving.

      I know you don't want to spend the money for a better block, but have you browsed the Corral forum for one? I see one every few months, but they are usually bored near the limit, or the price is almost the new price. You would need one close enough to ship feasibly of course, and many other non Dart blocks are older, more used, and have more risks. It is tough, I see one in my future too, and prices have gone up a lot in the last 5-10 years.

      My price on the dart block came in quite a bit better than Summit, but its still about $3500 more than free.

      a good machine shop can fabricate a sleeve and cut it in half the pin it in and align bore
      if I was going to buy a $3500 block I would find out where your thrust is coming from because it will take out that thrust no matter what the block cost

      Great news!
      I was suffering from premature stress.
      A re-tank, a shot peen, and a line bore and Dimas thinks the block will be perfect

      Tim had my back the whole time with vehicles picked out that he could rip to pieces in a hurry. Problem is, because of insurance, etc. I wouldn't be allowed to go do the rip and tear anyway. This would mean Tim would have been doing all the work. I wasn't cool with that.

      Anyway, it looks like its all going to work out saving Tims energy, and saving me $3500. I'd love a dart block, geez that's a lot of cash I don't have right now. And, do I need it for my power goals? Doubt it.

      The engine builder just bought himself an engine dyno, so he's in Minnesota now picking it up. He's hoping my motor will be the first motor on that dyno. Problem is, more delays while he's distracted building a room and setting up the dyno. Slooooow build.

      1. I hope the results are worth it.
      2. I really, really hope I have taken care of the hydraulic pressure on the torque converter (I'm as sure as I can be that this is fixed).

      sweet. so your motor will be the one that breaks his dyno's cherry! thats cool! it will also be the most powerful one he has had on a dyno at his place to date :D

      I ran across video's by Ford Strokers showing the shittiness (Is that a word?) of the Eagle crank.
      I sent the link to the engine builder.

      He sent me pictures of the same crank I ordered (Not mine, unfortunately). This crank is for a different build.
      Looks pretty good to me. He also mentioned that only the best of the cranks get selected for coating. That would make sense, as if you had to turn the crank to fix journal run out, you would be shaving the coating off. So, that would be a warranty claim on the new crank. These pics look good to me.

      I asked for a pic of the thrust surface (Last pic), and it looks good also.

      This is taking so long, I'm now faced with fixing the piece of crap I'm driving. It barely starts, but has a new battery. I guess I better start diagnosing and fixing since it sounds like my crank might not show up for another month.
