    Default HARD CORE CHEVY DUDES: I need help!!

    My Brother called today and he has an aluminum block brought to his machine shop that another machine shop severally screwed up.
    It is a ZO-6 Corvette "427". The other shop pressed a new sleeve into a cylinder with too much interference and cracked it in about 4 places on a couple of cylinders and then called the customer and said tough luck
    He (my brother) has a big enuff machine for the job but doesn't have a cooler on it. He would like for me to try and fix it.
    My question is does anyone know what material this block is made out of??
    This is a higher stressed area and I would like to get it right the first time if I'm gonna go thru all the pre and post heating hassle.
    I also understand that this is a relatively expensive block so it should be a pretty good chunk of change if I can voodoo it back into one piece
    I do big castings all the time but at this time I am open to any and all suggestions on filler material and procedures too. I don't want any surprises here just success....my family name is riding on this one
    BTW, I ain't got no oven so don't go there

    Cool

    I would say the "other" shop should cough up a new block, they screwed it up. Just my thought. I have fixed screw ups from some machine shops over the years since it was their fault and they made it right...Bob

    I am a ford guy, but I would never try to fix a block like that.

    I would call darton and see if this would work, their MID system.

    If that was a standard 300hp motor then I would say go for it, but its not.

    Whole thing sounds kinda odd, the shop that botched it in the first place should pay unless it was a "Cash" job.

    Thats what shop insurance is supposed to be for.

    I think the block is cast aluminum. Funny they didn't ceramic coat the exsisting sleeve and rebore it as apposed to jamming in a new sleeve.

    i UNDERSTAND ALL THAT!!! But does anybody know the material?? As for whether or not to do it? from my point of view of course I'm gonna try it.
    The guy got screwed for sure and he might be suing the other guys for all I know but even then somebody is gonna try to save this puppy someday anyhow just because of what it is. If I found it in the junkpile I would drag it home and give it a whirl for sure...basically an aluminum big block.
    Superdave... its gonna get a sleeve, but you still have to weld it before you can do that. The sleeve will be a special size on those cylinders also.
    If this was a aftermarket block no question about doing it and this one is pretty out of the ordinary.
    Thanks for all the replies anyways!!
    We might not have any hardcore late model 'vette guys on this forum

    The MID system is not a standard sleeve.

    here is a pic. If the block is cracked on the outside then good luck cuz im sure that thing is super thick but if its on the inside the MID may work but its pricey.

    I just think it would suck even more to weld it up and have it not work and then your out your 2k block plus 6k for the rest of the motor.

    It has to be welded to be saved.
