    2020 is here!

    Oh wow! Everything has to change I guess. I applaud the decision to not sell to a big corp. As you and I know, many forums have been ruined doing just that.

    LBZ: LBZ Cracked Block

    I knew you guys had trouble. Hate hearing these things. There is sooo much inside politics now as well. I see things on the daily from big outfits that are just embarrassing. Not related to D&J, but rather the fuel delivery side of things. Things that are not what people are told they are...

    LBZ: LBZ Cracked Block

    I heard a few have failed. I have a customer making 2k at the rear tires and his hammy block is ok so far. Im really waiting to see if we can get aluminum block prices down.

    LBZ: LBZ Cracked Block

    The Cummins crack too. Actually they tend to explode a big chunk out of the bore. I cant imagine a modern Cummins build for big power without sleeves. Unless it is one of those Hamilton extra thick aftermarket blocks. Of course it would be nice if we had more guys sleeving the duramax for the data.

    LBZ: LBZ Cracked Block

    Throw everything at it. LML block and sleeve all 8 with ductile dry sleeves. That will take your cylinders from roughly 30k psi strength to over 80k psi and add ductility. :thumb: Its also very affordable. Dry liners still use the parent block material for support Not enough meat is removed...

    LBZ: LBZ Cracked Block

    One caveat; dont use repair sleeves. Use the good stuff made for performance. LA Sleeve, Powerbore, Darton. Those can take a lot more cylinder pressure.

    LBZ: LBZ Cracked Block

    LA Sleeves makes a Duramax part. Stay away from Melling though if you go with sleeves On the deckplate stuff you always sleeve em, but that requires longer head bolts and pushrods, so a little more expense. Im not sure how that would effect the intake and other bolt ons either.

    LBZ: LBZ Cracked Block

    Maybe sleeve that block and keep going? Cummin guys use Darton, Powerbore and a few other companies for a supplier. I cant imagine a high powered cummins that would not be sleeved in todays world and live too long.

    Duramax block strength

    Yes, this! Sleeve that bitch with ductile iron or steel. The cast iron block will crack cylinders. Ductile will flex more before cracking. I have seen a ductile sleeve placed in a vise and squeezed and then return to its normal round shape. Then they tried the normal cast iron sleeve and it...

    PPEI Next On The Chopping Block???

    Ships! By far the worse. Just one of the world’s largest container ships can emit about as much pollution as 50 million cars. Further, the 15 largest ships in the world emit as much nitrogen oxide and sulphur oxide as the world’s 760 million cars. Their engines run 24 hours a day and...

    RIP Jessi Combs

    Yeah, very sad..used to watch her on TV back years ago. The extreme progression of the direction of things is bringing additional risk. She had a record of around 400mph and had gone right at 500 already in a single pass. They were trying for 619mph when it went bad. :( Rest in Peace Jessi
